Knowledge is potential power, but acting correctly upon that knowledge is what truly gives you the power/freedom to succeed.
Do you know anyone who you view as more successful than you even though you feel like you’re smarter than them? What’s the difference between you and them? The actions that they took (and you took) to get to your respective spots in life.
Don’t be bitter. You can’t change the past. But you can do do something about it now to improve your situation. We can all win in life. It’s not a zero-sum game.
