A success is it when you can stay real and still have success, but are not afraid to post your fails also...
We all learn and if we don´t say what we do wrong, how will the people learn? 
It´s nice to show off, but even nicer to be a good teacher and actually be of benefit to the others...i see so many chicks recieving tons of likes, they could be of service but like it more to have this social networking as their mirror where they make themselfs beauties..
