I've had a very similar realisation recently. A lot of what I spent the last 5 years doing has largely been to reach a state of security where I feel I 'no longer need to worry'.

Due to a death in the family, an unfounded health scare and a rather paranoid money scare it's been made quite clear that this utopia of 'secure' does not exist no matter what I do.

It has lead to a reduction in stress in some ways since the pressure to maintain everything and keep it safe is less if 100% confidence can never be reached so chasing it is pointless.

I don't know if you've had a similar experience but I'm currently at the stage of re-evaluating what I value since if some things (like wealth and health) are unavoidably temporary then the sacrifices I'm willing to make to maintain them are less than if they were assured or permanant.

I'd be curious to know how this has effected your outlook on life as I'm just starting with this now and it has certainly left me a bit lost. Although I don't think that's a bad thing.

Sorry for the slight ramble, just been very much on my mind at them moment.
