This is highly personal depending upon your likes. I can offer the following:

I am the kind of person that wants to retire at the first moment available in life - so I say. Not that I don't like working, only that I don't want to invest a single minute more than necessary within my life. That said, I was laid off for upwards of two years in my life, before I could find employment.

For the first twelve months, life was great. Bills were paid, I could do anything I wanted day to day. Next six months, life was good, bills still paid, but something was missing. The final six months, I was climbing the walls, needing something to occupy my time. Enough was enough.

I had movies, computer, games, forums, friends, etc, but it wasn't enough to then fill the huge hole I was feeling. People need a purpose that occupies their time, whether a cause, a hobby, or a job/career, etc, whatever.

This is a personal choice. NO one can make this up for you. You either feel it, or you don't. But it's up to you to FEEL it in reality.
