My definition of success is to live your life in a way that causes you to feel a ton of pleasure and very little pain - and because of your lifestyle, have the people around you feel a lot more pleasure than they do pain.
Once you have mastered time, you will understand how true it is that most people overestimate what they can accomplish in a year - and underestimate what they can achieve in a decade!
One reason so few of us achieve what we truly want is that we never direct our focus; we never concentrate our power. Most people dabble their way through life, never deciding to master anything in particular.
