The Hardest Thing is also..

not to point fingers..

its only easy to put the blame on others when things don't go your ways.

Just when you point a finger at someone, please be aware than the other four fingers are actually pointing back at yourself. It is always easier to be mad at someone else, for something he/she didn't do and even worse: for something he/she didn't do to make you happy.

Happiness grows from within. Please be happy yourself and Never rely on others to make you happy. because you don' live for others, you live for yourself. You can only truly love others when you start loving yourself. :)

Don't live in a world of self-fulfilling prophecy. Be open-minded, accept constructive criticism open heartedly.

When you fail to take criticism, you are one step back from self improvement, further to succession in life.
