Is it possible to go from average to hot looking?

I am a guy (23 yrs old) and I am not the greatest looking. I am not ugly or anything just kind of plain-average looking and there is this sort of unhealty look to my skin (dry, paleness.) However, I think I have potential to look better. I want to look more eye catching for the girls lol and also feel better about myself. How could I do that? How could I make myself look healthier and more attractive?..If possible.
