Maybe they don't motivate themselves because they think this is what they are, their views about themselves knows that they're not good or belittling about themselves when comparing to other people that are ahead of them. It seems that they didn't know about who they, they hid their undiscovered talents because the other person is better than them. They feel discouraged when someone already have a similar talent that is better than them and sometimes feel envious because the other one has higher praise than them. And that makes them comparing to themselves to other people because of insecurities they have even they knew that they can do it no matter what. They shouldn't compare themselves because that is the root of depression, having insecurities like thinking that they don't have purpose in anything, and feeling hopeless about that is what they are. instead they need to know who they are and what capable they are just to find their undiscovered talents, happiness and contentment than just compare what ever reason because of what they are capable with. What is the purpose if you aren't capable like the others if you are capable doing yourself? then think that every person is unique, it has a different role and objectives. Think who you are and what are you capable than forcing yourself to be someone else because you think yourself is different to others. Comparison never works that makes people having insecurities instead finding yourself who you are.
