That's one of the ideas presented, and one that I agree with. That's part of why I think it's important to have people around you who are supportive in general, but also people who have similar goals and dreams. No matter how abnormal you are, there are probably many out there who can relate.
But that's only part of the post, and Sebastian seems to indicate that "being different" means not living the idyllic suburban family life. And not because he doesn't want it, but because he's driven and wants to succeed (like where he talks about $40m as being his number). And this is what I disagree with; you can be driven and successful and still have a happy family life. You can even live in suburbia! There are literally millions of millionaires in the world. There are almost a million households in the US with net worth of more than $5m. Most of those people live normal family lives. They don't all float around continents writing blog posts and attempting to win the lottery by trying to start a bank one month and sell a $2m government contract the next.
In fact, now that I'm thinking through this, I think what bums me out about this post is the idea that it doesn't really matter what you do as long as you get rich. I doubt Sebastian has any real interest in starting a bank or fulfilling a huge government contract. He just wants money, and it's not even clear why. I don't think that's a healthy way to live, that's all.
