Although this is directed at artists, this mindset works for anyone! Is their a new style you have wanted to try? Maybe a new medium or instrument is calling your name! Just try it! Do. Be. Create.
The longer you wait, the less time you will have to try, and the more regret will build up. Both of which are not healthy or productive to you! One thing I always tell people afraid to go for it is that no one cares or has to know anyway! You are not Michael Jordan so there isn't a massive weight on your shoulders when you fail. You just scrap that idea and try another. But if you never get around to trying, the idea will go to the grave with you.
