Answer:
You typically push past your personal limits when you are tired or worn out. As an athlete I tend to do this a lot, whether it’s in practice or in a game. One time I pushed past my personal limits is when I came back home to play football (soccer) on break, and ended up playing in a tournament with my team. We had made it to the finals and the other team had their two biggest, most physical guys marking me. They ended up stepping on my foot a few times and getting a bit too physical resulting in fouls, which I typically shrugged off, but one time they got me right in my toe joint. This made it extremely difficult to run and kick the ball due to the severe pain in my strong foot. I was also really tired considering I had been putting a lot of effort into making runs as a winger. To make matters even worse, my team had nobody to sub on for me, considering I’m the only one my coach uses for left wing. I ended up playing through these conditions and winning the tournament with my team, however I ended up being injured for the next 1-2 weeks.
This is more of a personal question but since you asked I'll answer
