Still swimming

Went for a 60 minute swim today. I went later in the day because I thought that way I could have to pool to myself. Except there was way more people in the pool later. I was going to just a have a short, slow swim, but for some reason, with all the other people in the pool, I felt like I have something to prove. So I swam hard for 60 minutes. It is interesting that people's opinion matters to me. Especially when (without my glasses) I cannot really see them therefore I have no idea who they are. And yet - I try to out swim them all. I'm not always faster, but I usually can do more laps and I don't stop between each lap. For some reason, that matters to me. I'm not sure why.
