I have a friend that is very smart in certain areas, but very dumb in others. He has no emotional control, is very charismatic, and couldn't find the discipline to get through highschool calculus let alone college. He had a job earning 50K a year as a phoneman but hated it. He quit, moved to California and started selling driveways, house remodeling, etc. He loves his new life and seems to be doing very well.

Maybe your friend just needs to mix it up. Or maybe your friend is suffereing from depression. Professional therapy?
