Both but mostly options

Options *trading* and not options investing. I have the 'casino mindset' in that you should only trade with what you would feel comfortable losing. Find that number and don't exceed it. When I have a bad day at the casino (or even options trading casino) then it's best to take a break and come back when you got the right mindset (don't chase loses.)
