It's amazing how much you can accomplish if you start without needing anyone else's opinion. - Alex Hormozi

Entrepreneurship is about acquiring skills, beliefs, and character traits. To advance, I find that we must determine which skills, beliefs, and character traits we lack. Most times, we simply need to improve.

There's only really one belief you need to win:

Belief in your ability to figure it out.

That's it. Start - you'll figure out the rest.

If you're willing to die for something, than you'll certainly be willing to work really hard for a long time for it. Which should explain why some people are willing to work 24/7 to make their dreams a reality and others aren't. It's not discipline - it's purpose. Some things are important enough they're worth suffering for.
