Also, how do you work on sprinting faster? Just do sets of sprints back and forth?
On a different note, how do I know if one color "matches" another? (I've been going by two rules: If it's black, anything will match it. If it's [color], pair it with [a different shade of same color], or else black. Apparentely this is deeply wrong.) And why the hell is it a sin to wear black shoes/belt with brown clothing, or vice versa?
