I agree with this. Clearly you aren't happy with the life you're currently living, so change it completely. Do something exciting.

You may find it brings a new desire to live when you actually have to work to stay comfortable. There are many options, off the top of my head I would say fly to India with very little money and try to make a living. You have your savings as backup but try not to use them unless you really have to.

I realise it doesn't apply to everyone, so perhaps this isn't the answer, but at least for me excitement is what keeps me going, without it life really is quite boring.
