is it really important?

[The Brikk]

I was playing on filt tilt (0.05/0.10 cash game) the other day when this situation happened :

I was on the small blind with 33 and just to mixed it up a bit i decided to make a standard raise with 2 limpers. The first limpers called and the second one fold. the flop came K T 8 rainbow. I bet about 2/3 of the pot and the guy raise me three time my bet and i finally fold. I was pretty sure he was testing me but i decided to respect his move and fold.

My questions is : Is it really important to be able to add those kinds of play to move up in the lader or should i sticked to my own style and what's working for me???
And what you guys would of done differently???

Thanks!!!
