5. Despise other’s success
Mentally strong people are very much focused into their own life and goals. They don’t care much about other peoples’ success. Yes, there are some who genuinely feel happy for the success of other people. That kind of emotion takes a real strength of character that some mentally strong people show. They never resent people for being successful. However, they might just note down the reasons other people achieved success and use it to become better themselves. Mentally strong people are willing to work hard, and pave their own path to success. They don’t want any shortcuts.
