if you wanna make money from poker I'd say take a shot

Keep learning the game while you play, deposit at least 75$ on a poker site and grind it up (and btw if you go broke don't get super frustrated, just wait until you're ready to try again... I've gone broke 3x and it's possible i'll still go broke... I'm also starting out btw)

Don't play with scared money though... It will affect your game, playing poker through your emotions is a recipe for disaster

Use proper bankroll management, and you should be fine

as for which gametype it's all your choice... do what you prefer, some prefer cash games, some prefer STT/MTTs, some prefer omaha, others prefer NLHE
