i think way too often us men put all out self-esteem eggs in the basket of how much we earn. in fact, most guys whole self-image and well-being is based on their job and salary - take one away (or reduce pay), and they spiral into depression. Most people are extremely fragile.
I used to be guilty of this and the thing that helped me move away from it was, firstly, going through a number of upheavals over the course of maybe 5 years, from having my high salary cut, to then leaving a job and starting various businesses, some of which failed and some succeeded. I took time to keep reading, listening to podcasts and growing.
Each time, i would anchor myself in the things that were important, my family, being useful to them and reminding myself that a number on a bank account isn't the main thing, it's the actions and positivity and value you bring to people around you.
It is hard to feel like you're a man when you don't make much or are on a downswing, but we can always focus on working on ourselves and also build self-esteem by becoming good at other skills and hobbies
