What are your greatest goals in life? What achievements would you like to have for considering yourself a successful person? Just imagine all of this clearly in your mind and now answer to the most important question. What steps are you taking for reaching that goals and living your life to the fullest?
Try to observe yourself for a while and see whether you find yourself just constantly talking about your amazing plans instead of starting to make them a reality. The truth is that you can't build a reputation on what you are going to do. Your actions define who you are, nothing else.
