To those eager to succeed, young or old, and are disappointed that you just aren’t there yet, or maybe feel lost in life in general; my advice will probably sound cliché but experiment a little.
You still have more time than you think.
Wander a bit.
Tinker with stuff. Break things. Fail. Try again.
Don’t force yourself to pick something. Get lost in options and feel comfortable not knowing what you like.
Experiment and let yourself evolve into finding what you like through that experimentation.
