NL, LIMIT, or OMAHA? or ALL 3 ?

[JDMcNugent7]

I was wondering if you guys thinks its a good idea to focus on just one particualr poker game, or play a bunch?

Right now i play NL only, no other games at all, i do very well in NL, but wonder if i should play Limit and omaha and other such games too, i know how to play them and am actually pretty decent at both, but do u recommend concentrating on just one or many ?
