I struggle a lot to get my work done. I just can't concentrate well and my attention tends to drift -- i.e., I can't sustain my attention. I know I'm capable of doing more than I'm currently doing, but my attention & concentration are holding me back (IMO).

I hope that medication will help me concentrate better so that I can get my work done. I'm just falling *too* far behind at work, and it's not pretty.

My boss had recognized that I'm capable of doing great things, but he is concerned that my work is taking too long to get done.
