I agree with you about the charitable donations - those should be kept to ones self - but good for this guy for doing this. I’d talk it up a bit, too!
I understand the idea of self-promotion. Maybe he can write a book about his experiences and try to make even more money. Again, I think what he did is admirable. I just wouldn’t post pictures of myself burning my mortgage slip, etc.
Vanity is a tough sin. People that draw attention and want praise for their good deeds bug me. Before I went to college (over 25 years ago) my uncle told me about how my dad paid his way through college. My dad was the oldest of six. Family was poor Irish-Catholic living in the projects.
My dad got into Boston College. He lived at home and took the T to classes. He worked 3 jobs - food service at the school, a car wash, and a meat-packing plant (as a side note, to this day, my dad won’t eat hotdogs after seeing them made in that plant). After he graduated he went to OCS and became an officer in the Navy.
The point being, he didn’t brag about this or beat me over the head with stories of how hard he worked. He just did it and drove on with his life. It took my uncle telling me to know about those jobs. I knew he was in the Navy of course. Anyway, that made me work extra hard to try and earn a scholarship to college. I did (4-year ROTC) and my parents didn’t have to pay a thing. I’m a few months away from retiring from the Army.
Sorry for the rant. The world could use more people like this guy, but then of course all the restaurants would go out of business.
