2. They know how to forgive and let go
Mentally tough people realize that forgiving others and letting go of grudges will make their lives easier. They don’t allow past regrets and toxic people to ruin their happiness. These people are mature enough to forgive others for their mistakes even before they get an apology. Forgiveness doesn’t mean accepting their actions, it means moving on without dwelling on the past. Anger and resentment create stress in our minds that prevent us from thinking logically or acting intelligently. So forgive, forget and move on with your life.
