People respect you. They ask for your help when they're in crisis mode. They ask your advice.
If you run and avoid when things are difficult, you'll be happier short-term.
Keep running, and you'll be a disappointing 40-year-old. Keep running and you'll be a sad 50-year-old. Keep running and you'll be a pathetic 60-year-old.
It's better to stick. If you stick, other people will respect you for it. You'll respect yourself for it. That counts for a lot more than you think.
