Work that I did on my house that I lived in for over 30 years. I've been in my current house for seven years but it hasn't needed anything done yet. I'm not as interested now in participating in repairs and re-dos.
Finishing sewing projects was also a source of pride for me.
I play piano but the only time playing was a source of pride was when a dear friend asked me to play for her wedding.
I have to admit being proud of rearing wonderful children despite some daunting circumstances and events. Women three. We called ourselves that for a while. Nice memory.
