"I don't count my sit-ups. I only start counting when it starts hurting because they're the only ones that count."

-Muhammad Ali.

It’s hard to measure progress when it’s easy, but the trouble is that you need to learn your limits. If you’re not tracking where you get up to, it’s going to be very hard to determine if you’re improving. You might be trying to discover your weakness, but you need to recognise how that weakness might occur. But this can vary depending on other environmental conditions. When you get used to something, you might have a chronological clock to be able to track how long it takes you to perform a certain number of tasks. Or it may be likely that you have someone else to keep track of this for you so that you can focus on keeping going. It’s OK to push yourself but pushing yourself too far will take longer to recover to a medium that you’re familiar with. But on the other hand, it does show that you’re not willing to takes things easily. But it is a shame that you have to suffer to achieve what you want.
