4. Give up after failure
If there is one thing that you have to admire about mentally strong people then it is their never give up attitude. These people are willing to keep on trying and fail for a number of times. As long as they end up learning something from their failures, they will keep on failing until they have learned enough to finally achieve their ultimate goal. That’s the kind of person they are. In fact, everyone who has tasted success has had to experience failure in some sort of way. Failure is what builds up a character and getting back up after failing is the biggest character of mentally strong people.
