This world rewards actions, not intent. Too many of my friends are caught in the trap of learning too much and not using any of it. It’s easy to learn but when you try to implement you might make mistakes. And they are not willing to take that chance. This could be you too.
How many people who are dumber got farther in life than you? How many people that are not half as good as you are living a better life? Overthinking is putting you on the bench full time, while others are taking action.
What are you afraid of? what is the worst that can happen? I’d like you to check out this TED talk by Tim Ferriss. In it he explains how he deals with fear, it helped me a lot. I hope it will do the same for you.
