Blogging - Inspired by xkcd.com/458/

Is it possible to lose that feeling of regret of having said something?

Would it be better to refrain from saying something you feel, just because you might regret it later?

Can we go through life doing just one or the other, saying everything we feel or holding everything back because we just might feel bad if we don't?

Step outside the comfort zone, confront the unknown and see what happens. Forget the 'what if's'.
