The difference between ambition and longing is that ambition is goal orientated,
longing is source-orientated.
Ambition means there is something to achieve "out there."
It depends on a goal, there is a motive; hence you can be rational about it.
You can figure out weather it is worth achieving or not.
It is not a question of feeling, it has to be calculated.
You have to move in a certain direction cautiously,
because the world is very cunning and everybody is trying to achieve the same goal
and there is competition. You have to be cleaver and cunning, very cautious.
Longing has no goal but it has a source. The heart is the source.
OSHO
