You need to set up definite goals to reach where you want in life. Remember even gps needs exact address to reach the destination.

Expecting to be highly successful in life without clearly defined goals is like moving in a car and expecting to reach exact destination really fast without knowing where to go.
A car equipped with fastest engine, latest software and best features, capable of giving works class performance won't take you to your destination if you don't enter exact destination in its GPS.
Similarly your highly effective brain and great body can't help you achieve your goals unless you define those clearly.
This is what defines the difference between small random achievements and world class results.
