LF A High Rank Player to Coach Me (Macro Mechanics)

Hey! I decided to make this forum post to ask for any high ranks (Platinum +) to possibly coach me in Macro Mechanics. I enjoy eating scrubs and getting full like anyone else does, but I lack the very skill of thinking about the big picture. So I wanted to know if possibly anyone can either casually or seriously teach me more about the game's macro mechanics. I want to be able to quickly see what little things I can do that will positively impact a bigger picture (like destroying the nexus.) I don't want to take the "easy way" into anything, and I am willing to spend as much time working at is as anyone is willing to help me for. So thanks for reading!
