Answer:
Fitting-In can be explained as the act of trying to always follow the crowd or a trending way of doing things.
Fitting-In can be a handicap if an individual cannot be himself, as the person is always trying to be like the crowd and the person may never be able to express himself or be original.
In order to avoid the problems of always trying to fit in, some one needs to learn to trust in himself and make decisions he is confident in.
A person can fit in and be different, by knowing the trends of things happening around us but still being original to one's self and identity.
