Have you ever wondered?

What would happen if you threw caution to the wind and just rolled with whatever life landed in your lap?
I wonder lately if I've become to obsessed with safety. Financial safety being a big thing. There's a bit in my head that used to not care so much, and was happier following my impulses. But these days I seem to have convinced myself without a doubt that I AM STUCK.
I can't change anything, because then I wouldn't have a safety net. I work in a role I dislike enormously, but it's SAFE - it's permanent, it's all but guaranteed. It's not budging, and it brings in a set income, and I can pay the mortgage and most of the bills with it.
I have been looking for new jobs all day. There is a potential job just down the road from me. I'm trying really hard to bite the bullet and actually apply for it.
But I'm scared. Because the income will be smaller and I don't know exactly what the flow on effects will be. And I'm scared.
I never really thought that applying for work would be a risky thing. It is when it means you have to leave what you know and do something else, and when that something else comes with a lesser implied $$value.

Ack, I think I just need to man up or something.
