I’m not saying that you shouldn’t do a startup and strive to grow something big, amazing and self-sustaining. If it sounds like a challenge, then go for it, even though it will be hard and probably make you very unhappy at times. Don’t do it because you expect that there is something magical waiting for you at the other end, some state of nirvana for the rich and successful; there is always something next to attain. The journey is its own reward; if it isn’t, you’re on the wrong path.
Truth. Remember: You've got zero lives remaining.
