Thanks for the article, I see that point 4. is something that I have neglected. I should set some plan and goal and focus on a key points that I want to improve. Strengthen abs, build stronger chest etc. Also when I read your first point I actually realized that I have exactly the opposite problem. I kept low and did not raise my bar, sticking to lower weights etc. I think I need a bit more courage and get some load on :D I had a minor back injury and a knee operation but I should take the courage and try harder step by step. Right now I am not making much progress but rather keeping what I build under supervision of a personal coach.
