Should I be concerned about what appears to be a mistranslation?

I have recently felt very inspired by "I know I know nothing." It's a quote from Plato's Apology that is allegedly from Socrates. I recently came to find out that it isn't an accurate translation, should I let this effect me? I'd considered getting it in a tattoo as well, what should I do? I try to be logical, facts oriented, correct, etc. Does anyone have any other quotes pertaining along similar subject lines? The way I interpret the quote is that this learned man affirms that he doesn't know anything at the end of the day. Where to go from here? Abandon the plan? Screw the mistranslation? Find a new quote?
