I consider myself beyond lucky.
I found something i love to do, I never have to wake up angry or upset about my day job.
The best advice I can give anyone is to let all those fears go! Go after what truly makes you happy. Life, work and love. You will never be disappointed going after something you are passionate about.
I think the biggest disappointments come from the "what if's"
Be happy knowing you made the attempt to pursue what can potentially make you happy. Instead of wondering what could've or would've happen if you would've tried.
There are people who play the game and people who sit back and watch who are you?
