You should learn push / fold strategy. You can find decent charts on forum. In a nutshell in modern poker there is parameters which commands your game.
You need to act according to things above, you are playing in your card range which is defined by your stack size position and table action. If you are playing for UTG in early phase (deep 20+bb) you should not play under AJsuit, but when you have under 10 blind you will shove ALL IN A5s + from same position. Turbo tournaments are specific as they are requied much more math use pot odds
in first place, you will need to go all in with any two cards, sometimes you wish to call with any two cards. I would consider you to start play 0.10c 360man so you can apply P/F chart, on those tournaments you will no loose a lot, so you can still practice how to play!
