1 Oh dear, I think that comparison is sometimes very constructive, because if I see that somebody is better than me in some respect, I strive and actually make many efforts for getting equally good in it!
2 IMAO each person is too unique to be compared with others. Everything is balanced and if one is weaker in something he/she is certainly stronger in something else.
4 I think that comparison makes for striving for something supported by one's ambitions, so it's not bad in fact, as everything is perceived in comparison with the other
