The most common mistake I see is people suck at tower last hitting.
+ they are pushing too early since you gain more gold and exp when you're next to your tower than their.
Pantience is the key word. More gold -> Better items, Quicker exp so you get lvl 6 faster and then you're ready to kill your enemy unless you see that you're able to first blood and then just push push until enemy is back.
+ When enemy got like 30hp and you run after him through the tower and the tower hits you like 3 times so you're pretty much dead by then so you should never run after low hp enemies because with bad luck they get gold from you and then they are harder to kill next time.
