NVDA L because of in-proper mindset

started off green with in my trade allowed greed to take my profits away, then i jumped into another buy in which wasnt the right mindset to think, because i let my ego take the order. now im swinging contract and seeing if the lord will forgive my mistakes, with a minor loss. buy in 1st $510 sold, after for $415, 2nd buy in $480 i want to sell for $450
