ADD and ADHD are liberal-speak for "requires more stimulus than the average individual". People are being diagnosed with it left, right, and centre, nowadays. Still, if you feel that you have such a condition, then Ritalin is not a good idea. A friend of mine was on Ritalin for a good four or five years, and it just left him lethargic and placid. He stopped taking Ritalin about three years ago, actively set out to fix whatever condition he had himself, and is now a much more lively individual, while maintaining an ability to focus on things which aren't immediately exciting/rewarding/interesting/whatever.
