I used to play tennis in the past. Now when I think about ways to spend my free time, I started thinking about playing tennis again. I do not know yet if I am going to play it again, but maybe I will. One thing I was always struggling with while playing tennis was the lack of tennis backpacks. Not all the things I had could fit into my backpack. Playing tennis always required me to bring an extra pair of shoes and a few other accessories I needed. If I am going to start playing tennis again, I will have to start thinking how to pack my stuff in such a way so that I am happy with it.
