Take 2 people...
Same age, same high-school, similar grades, both brought up in the same town.
By the time they turn 30...
One is thriving, with a successful business, a loving relationship, and a lifestyle to die for.
The other is living week-to-week in a dead end job, deep in debt, stressed out, volatile love life, and still wondering what the purpose of life is.
While one is working toward self-mastery and doing what they love to.
The other is working toward the weekend and doing what they have to.
While one is building the life they dreamed about.
The other is having doubts about their life choices.
Same starting point.
