I am a loser, my business failed, and I am 30 years old. I accept my parents' help. Everyone came to scold me, old loser.

Failure is not terrible, but losing morale is terrible. Summarize the experience and lessons, start over or change careers. Qi Baishi gave up carpentry in his forties and went to the north to paint, becoming a generation of famous teachers, which is the best example. If you are willing to work hard, you will always succeed. Maybe I failed just because I didn't find my own way.
