I don't know if it is a subconscious thing, or the real deal, but sometimes when I am in a hurry, or am exercising or doing something physical, I can push myself further. When I try to push myself normally, like by will power or thinking about something else, it doesn't work and I end up giving up. But if I say "Gate of Opening, Open!" I somehow feel the strength to walk/run a little bit faster or to do at least one more push up or sit up, etc. I have a feeling that I am just boosting my adrenaline somehow by shouting a phrase that is supposed to give me strength. But it's fun to imagine that it really works.

I'm just gonna bump this because I think I get it.

It's probably illusory fatigue mixed with motivations and beliefs that had an effect on ego depletion.

Ego depletion refers to the idea that self-control or willpower draw upon a limited pool of mental resources that can be used up. When the energy for mental activity is low, self-control is typically impaired, which would be considered a state of ego depletion. This can cause you to be less able to persist on a difficult or frustrating task such as running.

Illusory fatigue has a connection with Ego depletion in which ones ego depletion is severe enough that it effects the perceived levels of fatigue.

After you perceived it to be greater than it was due to your ego depletion caused by whatever reason, external motivation and belief (such as believing you have unlimited willpower) buffered the effects of ego depletion, allowing you to focus on pushing yourself harder to meet your goal.

But I'm just a kid, I'm not a psychologist. I'm terrible at explaining and my information could be wrong.

If you think you wanna read more about it, fwoosh
