I'm gonna talk to you about some things I've learned in my journey. Most from experience, some of them I've heard in passing, many of them I'm still practicing, but all of them I do believe are true. Life is not easy. It is not. Don't try to make it that way. Life's not fair. It never was. It is it now and it won't ever be. Do not fall into the trap, the entitlement trap, a feeling like you're a victim. You are not. Get over it and get on with it.

[00:00:28,079 --> 00:04:04,680]
So the question that we're gonna ask ourselves is what success is to us. What success is to you? Is it more money? That's fine. I got nothing against money. Maybe it's a healthy family. Maybe it's a happy marriage. Maybe it's to help others to be famous, to be spiritually sound, to leave the world a little bit better place than you found it. Continue to ask yourself that question. Now your answer may change over time and that's fine. But do yourself this favor. Whatever your answer is, don't choose anything that will jeopardize your soul. Prioritize who you are, who you want to be, and don't spend time with anything that antagonizes your character. Be brave, take the hill, but first answer that question what's my hill? For first, we have to define success for ourselves and then we have to put in the work to maintain it. Take that daily talent. Tend our guard. Keep the things that are important to us in good shape. Where you are not is as important as where you are. It is just as important where we are not as it is where we are. Look, the first step that leads to our identity life is usually not. I know who I am. I know who I am. That's not the first step. The first steps usually I know who I am not. Process of elimination. Defining ourselves by what we are not is the first step that leads us to really knowing who we are. You know, that group of friends that you hang out with that really might not bring out the best in you. They gossip too much, they're kind of shady. They really aren't going to be there for you in a pinch. How about that bar that we keep going to that we always seem to have the worst hangover problem? Or that computer screen, right? The computer screen that keeps giving us an excuse not to get out of the house and engage with the world and get some real human interaction. How about that food that we keep eating? Stuff that tastes so good going down, makes us feel like crap the next week? We feel a thardic when we keep putting on weight? Well, those people, those places, those things, stop giving them your time and energy. Just don't go there. I mean, put them down. And when you do this, when you do put them down, you put them down there. When you put them in your time, you inadvertently find yourself spending more time and in more places that are healthy for you, that bring you more joy. Why? Because you just eliminated the who's, the where's, the what's and the wins that were keeping you from your identity. Look, trust me, too many options. I promise you, too many options will make a tyrant of us all. Alright, so get rid of the excess, the wasted time, decrease your options. If you do this, you will have accidentally, almost innocently, put in front of you what is important to you. By processing elimination. Knowing who we are is hard. It's hard. Give yourself a break. Eliminate who you are not first. And you're going to find yourself where you need to be.

Instead of creating outcomes that take from us, let's create more outcomes that pay us back. Fill us up. Keep your fire lit. Turn you on for the most amount of time in your future. We try our best. We don't always do our best.

[00:04:16,899 --> 00:04:50,120]
Architecture is a verb as well. And since we are the architects of our own lives, let's study the habits, the practices, the routines that we have that lead to and feed our success. Our joy, our honest pain, our laughter, our earned tears. Let's dissect that and give thanks for those things. And when we do that, guess what happens? We get better at them. And we have more to dissect.

5
[00:04:43,980 --> 00:05:00,120]
Be discerning. Choose it because you want it. Do it because you want to.

We're going to make mistakes. You got to own them. Then you got to make amends. And then you got to move on. Guilt and regret kills many a man before their time. So turn the page. Get off the ride. You are the author of the book of your life.
Thank you.

我将和你谈谈我在旅途中学到的一些事情。大多数来自经验，其中一些是我偶然听到的，其中许多我仍在练习，但我相信所有这些都是真实的。生活并不容易。它不是。不要试图那样做。生活并不公平。从来都不是。现在是这样，以后也不会是这样。不要落入陷阱、权利陷阱、感觉自己是受害者。你不是。克服它并继续它。

[00:00:28,079 --> 00:04:04,680]
所以我们要问自己的问题是成功对我们来说意味着什么。成功对你来说意味着什么？是不是钱多了？没关系。我对金钱没有任何抵触。也许这就是一个健康的家庭。也许这才是幸福的婚姻。也许是为了帮助别人出名，在精神上健全，让世界变得比你发现的更好一些。继续问自己这个问题。现在你的答案可能会随着时间的推移而改变，但这没关系。但帮自己一个忙吧。无论你的答案是什么，都不要选择任何会危及你灵魂的事情。优先考虑你是谁，你想成为谁，不要把时间花在任何与你的性格相悖的事情上。勇敢一点，登上这座山，但首先要回答这个问题：我的山是什么？首先，我们必须为自己定义成功，然后我们必须付出努力来维持它。以日常天赋为例。照顾我们的警卫。保持对我们重要的事物处于良好状态。你不在的地方和你在的地方同样重要。我们不在的地方和我们在的地方同样重要。看，通向我们身份生活的第一步通常不是。我知道我是谁。我知道我是谁。这不是第一步。第一步通常我知道我不是谁。消除过程。通过我们不是什么来定义自己是让我们真正了解自己是谁的第一步。你知道，和你一起出去玩的那群朋友可能并不能发挥出你最好的一面。他们闲话太多，有点阴暗。他们真的不会在紧要关头为你提供帮助。我们经常去的那个酒吧怎么样，我们似乎总是有最严重的宿醉问题？或者那个电脑屏幕，对吧？电脑屏幕不断给我们借口不走出家门，与世界接触，进行一些真正的人际互动。我们一直吃的食物怎么样？味道很好的东西下周会让我们感觉很糟糕吗？当我们体重持续增加时，我们会感到疲劳吗？好吧，那些人，那些地方，那些事，停止给他们你的时间和精力。只是不要去那里。我的意思是，把它们放下。当你这样做时，当你把它们放下时，你就把它们放在那里。当你把它们放在你的时间里时，你会不经意地发现自己花了更多的时间和更多对你健康的地方，这给你带来更多的快乐。为什么？因为你刚刚消除了那些阻碍你了解自己身份的人物、地点、事件和胜利。看，相信我，有太多选择。我向你保证，太多的选择会让我们所有人成为暴君。好吧，所以摆脱多余的、浪费的时间，减少你的选择。如果你这样做，你就会无意中、几乎是无辜地把对你来说重要的东西摆在你面前。通过处理消除。知道我们是谁很难。这很难。让自己休息一下。首先消除你不是的人。你会发现自己处于你需要去的地方。

[00:03:59,139 --> 00:04:26,939]
让我们创造更多回报我们的成果，而不是创造索取我们利益的成果。填满我们。让你的火一直点燃。让您在未来的大部分时间内保持活力。我们尽力而为。我们并不总是尽力而为。

4
[00:04:16,899 --> 00:04:50,120]
建筑也是一个动词。既然我们是自己生活的建筑师，那么让我们研究一下我们的习惯、做法和惯例，这些习惯、做法和惯例会导致并促进我们的成功。我们的欢乐，我们真诚的痛苦，我们的笑声，我们应得的泪水。让我们剖析一下并感谢这些事情。当我们这样做时，猜猜会发生什么？我们在这些方面做得更好。我们还有更多需要剖析的内容。

5
[00:04:43,980 --> 00:05:00,120]
要有辨别力。选择它，因为您想要它。因为你想做所以去做。

6
[00:04:52,819 --> 00:05:23,519]
我们会犯错误。你必须拥有它们。那你就得去弥补。然后你必须继续前进。内疚和悔恨会提前杀死许多人。所以翻页吧。下车吧。你是你生命之书的作者。
谢谢。
