How do you motivate people ?

Over the years I have always wondered how people get motivated or have lack of motivation . Is it fear ? Is it a desire for success ? Is it just a never give up attitude ? Is it just accepting you are where you are ? Is it because of your parents did not motivate you ? Is it because you were given everything ? We are all motivated by different things and I really feel that the simple solution is to find out what motivate you to get up in the morning to get into the game .
