Chess Critical Mass

A while ago I heard that you cannot have more than one chess coach/teacher at a time. The tactics and advice tends to pile or hinder on the others. I wonder if that is what is going on. I have bought chess books, and played turn-based, found chessmagnetschool, been given advice by our members and our school's chess coach, and began reading Reassess Your Chess Workbook. But nothing seems to click. 

I think that I am expecting too much too soon. This is, after all, a lifetime thing no? Any advice would be welcome.
