Isn't the belief that life has no meaning a drive of it's own, giving purpose to those that claim to have none?
Aquabanianskakid,
That's one way to look at it. The belief I choose to hold true for my life is this:
The meaning of life is what ever I make it up to be!
There's real power in truly understanding that. Each one of us wakes up every day with a blank page. We can create anything we want with the time we have. Some people choose to follow the same old routine every day without doing things very differently. Others want life to be different that it currently is, so they go out and try different things every day, continually striving to improve.
Some people hold a really really big purpose in life like racial equality for South Africa as Nelson Mandella did. Others choose to hold a simpler purpose in life. Now one is not better than the other, good, bad, right, or wrong. They are simply different, and each contributes to the world in one way or another. Yet again, it's the same world, what's different is our perspective, and how we choose to see the world.
