“You may wonder how many people in the entire workforce are handicapped. The answer is: everyone.”
Everyone has handicaps - maybe you have a physical or mental one, or maybe you’ve never graduated from high school or college, maybe you’re too fat or too thin, too young or too old, maybe you haven’t had a job in a long time, etc. Whatever it is, know that while it is possible to have a handicap that will keep some employers from hiring you, it is impossible to have one that will keep all employers from hiring you.
Instead of focusing on your handicap (ie. the things you can’t do) focus on the talents you have and all the things you can do.
Of course, employers do have prejudices. However, these prejudices are a reflection of the employer and not you - when you find the right employer, these prejudices won’t matter. Employers tend to be most prejudiced against those who have been out of work for too long, those of different races, religions, or sexualities, those who are too old, war veterans, ex-offenders, and those with a history of psychiatric illness/hospitalization.
Get your mind off what you can’t do, and on to what you can do.
