What is the hardest truth you had to accept that made you stronger?

I'm too weak that I can not success any job or any work.

1. I don't have any girlfriend.
2. My job application was rejected by 100+ companies.
3. I do a simple job, earn $190 per month and work 9+ hours per day.
4. I am an average person. So, I have to work really hard or give extra effort to compete with superior performers.
5. I have to work weekends.
6. Sometimes my boss shouts at me. I keep silent and do my work as if nothing has happened.
7. I am emotional and love to help people.
8. I haven't cried in many years.
9. Life is unpredictable.
10. God exists. Though He doesn't have time to listen my prayers.
11. I haven't traveled outside my country.
12. When I get hurt, I feel frustrated and run every morning like ‘Forrest Gump’.

I want to be success in my life. Now what can I do?
