Run TP if you intend to carry from top. Learn the meta champs. Realize that as a top laner split push to win is always an option and requires the commitment of only one player (you), just be sure to ward up. Start playing Ryze and Nidalee, learn champs like Nasus, Irelia, Tryn, and Singed. That group covers your late game scalers, mobile split pushers, mid game hypercarries, and annoyance proxy farmers. Avoid champs that are common at higher level play like Lulu and Mao as they are used mostly as supportive top laners who allow the ADC to stay alive and in fights. This is NOT the strategy you are looking for to carry out of lower levels. Learn to utilize TP to the best possible advantage, learn to control minion waves and push ONLY when you are ready and have vision to allow you to do so safely, and improve your map awareness so you know when to back off for a tp counter gank, or push since there are 4 bottom and one mid.
