Life hack (for us over 30):
If you think back on your life 10 or 20 years ago. You will most likely see that you had endless opportunities that you either did not know of or appreciate.
Now, realize it is the same exact same today.
I'd say the biggest waste of time in life is trying to be "cool" and trying to fit in.
There's no bigger relief than not having to perform for others.
Life's about chasing the stuff you actually love, even when it's weird, even when it's uncool, even when nobody else gets it.
