There are tasks which I can never perfect. To some people, I may have done quite well in some parts of these tasks, but I know I could have done much better, but never to my best.
Perhaps, I need more time and concentration. Or perhaps, if you take away all my commitments, I would be able to focus.
There are probably too many things which I want and have to do.
It has been so bad that sometimes I can get thinking of two different things at the same time.
