"Do it like this...don't do it like that", people would always want to add their little cent to whatever it is you are doing...be it good or bad. There are always going to be people that would not agree with the way you do things or the things you do ...irrespective of whether you are right or wrong, people would always talk.

But I am human, how do I cope with that?

This is where I say you should know yourself and what you stand for. When you understand that life isn't meant for pleasing people and you know what you want for yourself then you are good to go. I feel only those who are not really stable in what they want for themselves would be shaken by what people say.

However, there are those who will have good intentions...listen to them and pick the ones that works for you. As for the others with no good intentions ...just ignore them. I'd advice that you grow thick skin though...because life comes throwing different things at you...so be ready to face it all knowing well "Who you are and What you want".
