Principles are ways of successfully dealing with reality to get what you want out of life.
Ray Dalio, one of the world’s most successful investors and entrepreneurs, cites principles as his key to success.
Write down what your one big thing is (such as identifying problems, designing solutions, pushing through to results) and why it exists (your emotions trip you up, you can’t visualize adequate possibilities). While you and most people probably have more than one major impediment, if you can remove or get around that one really big one, you will hugely improve your life. If you work on it, you will almost certainly be able to deal successfully with your one big thing.
You can either fix it or you can get the help of others to deal with it well. There are two paths to success: 1) to have what you need yourself or 2) to get it from others. The second path requires you to have humility. Humility is as important, or even more important, as having the strengths yourself. Having both is best.
