Have to versus want to versus get to

I think when we agree to complete work we all say yes because we are there together and don't want to be like no I'm just going to eat and sleep when I get home. So that leaves it to have a 50/50 chance of actually doing the work. Being told to do homework lets us know that we have the work and we got to do it. Because agreeing on it gave us a choice this doesn't. exploring in your own way is me sleeping, if I could avoid work then I would. I do my best when I am told what to do.
