For being a successful person first of all we have to know more about ourselves, then choose a goal and as soon as choose it we have to start to achieve it... But just hard working for achieve that goal is not enough... We have to prepare for reach that goal mentally, I meant if we can imagine that we receive that goal in our minds definitely we can achieve it in reality... Believe is the most important thing to reach goals... I meant if you try for achieve your goals days and nights but don't believe that you can reach them .... You really can't...
This is my idea :)
Don't forget, if you could not start today, you will not be able to finish it by tomorrow .The most difficult work is the " start"
