What is that something that you always thought would be cool to do/learn but have put off, don’t think you’ll be good enough, etc?
Why aren’t you going after it?
Too much money? Too much time?
I used to use excuses for things I’m doing now and still, unfortunately, use them for other things I would love to accomplish.
Push yourself. In all areas of your life, strive to be your best. Not for bragging rights, but to push and discipline yourself.
Do it before the opportunity passes you up. Learn that language/instrument, take up that boxing/karate class, pick up photography/cooking.
Go for it.
