Honestly don't expect an easy and fast climb to your ranks. Play with friends, be better as a teammate and player in game.
I do believe if you can play with lower elo player and win or lose, it will help you be better by improving you skills and learning from the mistakes of what not to do from those "not doing well"
Keep playing honestly, win or lose, practice as much as you can and don't take it seriously.
If you are taking it seriously, play with friends , solo que is a bitch, your going to be rolling the dice for each player with and against you. and its not fun when your ally trolls, AFK or disconnect.
if you have time, but enjoy the game, play bot for your first win, 200ip at most for 20-30min game, its lame, but it'll boost you moral IMO
