say "no"

It's hard to say "no" even if you know it's the right way...You don't want to offend or to have quarrel with someone. But it's needed! Especially in your work, when you have concrete vision and goals. Every single action on your way towards the goal must be committed to it. Otherwise why are you doing this? To make someone happy? Success doesn't always mean everyone is happy...

Good realization but can I do it?
