I agree with the vitamins and exercise. You can really feel a difference when you are active and have a good diet/ vitamins. Regarding the floor, we'll see if you follow that advice when you hit your mid 30s and have a wife who is quite content with a bed (joke).
I'm glad you found some motivation, but you're still not off the hook. Please post an intro. thread.
Welcome and good luck in the fastlane!
