Pyramid 1st and 2nd time

When we did the pyramid for the first time we went from 13 - 5. My start was horrible I really could have done better and I wish I did. I was at 10 reps 20 min into the work which really disappointed me. But with 7 min left I gave it all I had and I ended with 7 reps and nearly finished it. The second we did 10 - 1. I started better than I did for the 1st pyramid and I didn't look at how much time was left until it was a couple min away from the end and I was so close to finishing.  Rather than saying there's no point of trying I kept saying to myself I can do it and I can't stop now because I didn't put much effort in the fitness before. I finished at the end and I was so self satisfied and yet so tired but, now I know what I'm capable of and I'm going to try my hardest more often.
