Why is it so hard to make the thing that you want the thing that you need

Take study skills for instance.

We all need to learn to listen, take notes, study smart with notes and text, and remember.

IT is hard work, and requires us to put in effort to changing lazy habits. Well, we need it. Why don't we want it?
It's not only hard, it's often impossible. Money, common sense, safety, and the feelings of others may prevent us from getting what we want.

I may want a Mercedes, a pound of chocolate a day, and the love of a particular person. However, I don't need any of these, nor in the long run will I really want them.
Your question is confusing. Who do you want to convince that a want is a need? Are you trying to convince someone else that your want is needed?

It is like trying to convince someone that a luxury is a necessity. We need a certain amount of food to survive, but we don't need to eat our favorite foods (ones we might want) to survive. Likewise, we need to be clothed (especially in cold weather), but we do not need to have a wanted style of clothing.

I hope this helps, but I don't know if it will.
