Typical characteristics of focus with the appropriate age group.

1-5 years old too young to really decide what they want (this usually applies to 1-3 year olds. When they get to be a toddler they get pretty ambitious from my experience) 6-10 Primarily friends or family (when they turn 9-10 they start developing into their teenage stage) 11-15 Surviving middle/high school with decent grades/ going to a good college and making it big 16-20 is pretty easy to guess and so on

That's  a project for you to do. btw your teacher probably uses a plagiarism detector and if you do copy anything on this site she/ he will find out and instead of getting a good  or bad grade you'll  get a 0 no exceptions, and they'll  probably call ur parents. so do some research ask friends and fam to you.

Yes it does it plays a big role
