What is the maximum amount of roles a person can play in life- worker, wife, flirt, daughter, artist, carer, criminal, boyfriend etc?

There are roles we choose to play and there are roles that we've been placed into by circumstances or Higher Forces, positions we didn't really expect. So it comes down to your own sense of happiness, accomplishment and pride of playing each role.

One thing for sure, whenever you don't feel good, there's a good chance that you're not playing a very important role in life.

There is no maximum NUMBER of roles a person can play in life - different experiences come with time.

Depends on the person. Some can 

barely manage just one role, others 

are able to juggle endless roles. 

There is no limit. It all depends on what the individual can do and is willing to bear.

Right at this moment, i am a flirt, husband, son, father, brother, friend, employee, teacher, 

As many as you choose
