Talk About Tennis 2.0

Hi everyone, what are your biggest "pains and problems" as a professional tennis player? Is it injuries, or fear of losing? Or that you just get nervous in matches, or that you freak out too much in your training sessions? It'll be interesting to read.

I don't think we have any professional tennis players here - just fans.

As above, just fans.
But my greatest pain and problem is that, due to my lifestyle, I go through long patches in which I cannot play. And therefore, I lose too much of my (limited) skills when I am off court. The older I get, the harder it is to get back to any decent level. So, it is not only the aging, but also the training structure that I can no longer keep.
It now takes me at least a couple of months to return to a decent level. And by then, I have to go back to work.
