I've also noticed little coincidences.
Fate is something I'm unsure on. I do think that things always seem to find a way of working themselves out.
I've learned not to worry about things I can't change, something I learned after joining this forum.

I don't like to think that fate exists, because I would feel I don't have choice in my life. I also don't believe in any God or any higher power. But if I do something bad I do sometimes worry about bad karma biting me in the ass.

I think the saying "what goes around comes around" is quite true. And it is often too late before you realise this.
