I also struggled with F Major, and found a way that works for me.

What I also found is that when I struggle with something, then finally get it right, I then look forward to playing it - open G maj to F maj was a problem and appears in one of my favourite songs. Now I love playing it because I am pleased with myself for finally nailing it!
