After I finished reading this post it made me to think. It is very true that we often want results without putting in the work. There are many people today they are trying to look like they care about it or other stuff but few are just willing to go through those discomforts.
You also made a point about "filling the tank" and even when we hate doing it, and that is true improvement, it iw never easy but it is necessary for our growth
I think the moment we accept that discomfort is part of the process of development and growth then we can start moving closer to what we actually want in life.
And the more we avoid discomfort when young, the more uncomfortable life becomes as we age. We should be teaching kids how to keep themselves healthy, before hey are unhealthy.
