Nobody is better than you, although some are better in specific areas. Some of them are worth emulating. "Trying on" different emotions and roles can be good. It can bring out parts of you that you didn't know you had. If it seems to fit, walk around in it for a while before you buy it.
If you feel yourself slipping into a role you don't like, balance it out by hanging with different kinds of people.
To the extent possible, have a balanced diet of different kinds of people in your life. But the good kind, not the toxic kind. For example, I have a severe allergy to fascism. For me, there's no safe dosage. Sociopaths tend to make my head spin, too. In general, people who have been caught in the act of deliberately hurting me are to be avoided in future.
On the other hand, mildly annoying people are good exercise. Such as the excessively perky or dramatic. Or religious people who drip inspirational silliness in every conversation. They mean well, and help me to maintain my tolerance for irrational nonsense and superstition.
