Most rewarding, and the most frustrating thing in existence. If you try it you will likely lose money to start, but get a strategy down that fits you (it's different for everyone) and stick to it. Mine is small cap biotechs. Obey max loss tolerance at all costs and bail when it's obvious to, don't "hope" for it to turn around. As long as you keep yourself in the game and don't blow up you will succeed and feel achievement you've never felt before. Oh...and don't fall for the "gurus" selling services. There are a few really good people out there that want to show you the way, but stay 100 miles away from anything that says "rich" and "fast," or "turned X into XXXX in a few months." It doesn't work that way out of the gate.
