I don't know what success really is.
But to me success is when you're able to live the life you know you should be living deep down inside of you. When you're able to do the things you know you should be doing.
Instead of just following and doing things you were not meant to be doing. Things you don't want to be doing. Things you don't enjoy doing.
And to me, that's real success. No matter how much money you make. Or have. Or what your job title says. As long as you're able to live a life staying and being true to your true inner self, then that's success to me.
What's success to you?
