How do I git gud and escape tunnel vision?

I'm in bronze. I know so much about the macro of the game. I know how and when to rotate, I know how and when to take objectives, I know how to control minion waves, I know how to roam, I know how to control vision. I can play any champ I'm put on decently and can play very well on half the champions in the game. I at least have the same understanding of the game as a master player. I use mobalytics often and read all the guides and try to improve. I've watched all the league 101 vidoes. As soon as I get into a game I get tunnel vision. All I can do is micro with my champion and vision. I'll give myself that I'm fantastic with vision, but that alone does almost nothing to help me get out of bronze.

How do I escape my tunnel vision?
