You mean, you graduate from high school and it's been 4 years since then?
Decide what kind of work you want to do (regardless of long term or short term at this moment) and get some skills that will help you get that job. By saying "that job", it doesn't have to be just one type of jobs.
Or, go to college and pursue some education.
In any case, find something to do. No good feeling will come out of not doing anything. If I were you, I'd be bored to death.
