Coping with competition: Most twins have got complete unique qualities. If at all one is better than the other, there arises a complete constant competition among them. Parents, teachers and friends begin to compare the good and bad which does worsen the age.

Career choices: To each his own, if one is a brilliant student and chooses to be an engineer and the other one an artist, doesn't mean that the other one is in any way less in abilities. Career choice is a major issue among identical twins as people think they have the same aptitude.

Peer pressure: Peer pressure among twins arises when they are in schools and colleges. Their aptitude and change in behaviour is very closely noted. This usually happens when parents use to constantly pressurize him/her and ask them to follow the better twin. This creates a kind of harsh environment among them.
