Life is full of "what if" questions. What if I try this and can't do it? What if I don't like it? What if I just can't do it? What if no one cares? What if it doesn't work? What if people hate it/me/you? What if they laugh? What if it is the wrong decision? What if...what if...what if.
Everything we do can be preceded with a what if question. Stop. Stop asking them right now. The best answer to each and every one of these questions is "Who cares". Seriously, who cares if people laugh or hate something or if you get it wrong this time. Who cares if you make a mistake or choose a hard path or do something weird.
Each time you find yourself asking what if, instead ask yourself:
Is this something I really want to do?
If the answer is yes, do it. If the answer is no, then don't. Stop worrying about the possible outcomes and just keep moving forward. What if doesn't matter. What matters is not letting the fear of what happens next stop you from doing what you want.
