I hear you on that man. KNBA only caught my attention sometime after the one day PnD.
I am still young (relative) and only have 1 year of real money penny investing experience, but damn I learned a lot lost year. I saw myself pass my EoY goal on one play only to lose it all and more.
However, losses are only (completely) bad if you dont learn from them.
Lose, learn, win.
Too bad those losing and learning stages will exist for everyone who ever lives and cares to improve, hah.
