"Substantial gainful activity" is any activity or work where the person is performing significant duties over a reasonable period of time while working for pay or profit, or in work generally done for pay or profit.

Full-time work (or part-time work done at the employer's convenience) in a competitive work situation for at least the minimum wage conclusively shows that you are able to engage in substantial gainful activity.

Substantial gainful activity is not work the person does to take care of himself or his home. It is not unpaid work on hobbies, institutional therapy or training, school attendance, clubs, social programs, and similar activities. However, doing this kind of work may show that the person is able to engage in substantial gainful activity.
