We like doing things we are good at, right? There is the occasional challenge that appeals as well. But, overall who wants to continue doing something they feel that they are bad at it. Its no fun. Especially, if you are not forced to do it. Finding the personal motivation is most challenging! Self discipline! Doing it even though your head and body says "No, don't do it!" Can you imagine if we were robots and did everything by schedule. I don't think it would work. All those spontaneous acts that make life so special would be gone.
Ohhh, I really don't want to do homework! -Alice
