My general impression is that there are only three broad ways to be happy in life:

1. Genetically (i.e. your brain just works that way)

2. Luck into it

3. Iterate towards it (continuously)

The whole concept of "get job X and now I'm done" doesn't really fit well into any of those. A job could be a good iteration or you could get lucky and have it turn out to be a wonderful team/position/whatever, but the likelihood of your plan being "I need to do x" and then you do x and are then happy seems immensely unlikely. Like Samuel Johnson said, "Life is a progression from want to want, not enjoyment to enjoyment."
