Guys, i'm playing Pokémon White and i just got a Virizion, but it's nature is relaxed. Should i try to get a Virizion with one of the natures of the smogon page (http://www.smogon.com/bw/pokemon/virizion/uu) or i will be wasting my time?

I'm pretty noob about things like natures, IVs, EVs, etc. Thanks.
