A lot of progress in life actually tends to make you feel worse about yourself.
Training with people who are much better than you, reading books that make you feel dumb, challenging yourself with work that make you feel incompetent, being frugal and investing your money instead of spending it on more comfort and overall, treating the short-term pain for the long-term gain.
And the corollary is that people who struggle to get the progress. They won't actually be in a detail, only doing things that make them feel better about themselves and life in general.
