Thanks guys for your advice and support.
Yes,I'll try not to think ahead. I'm reading The Power of Now by Eckhart Tolle, which is kind of helpful. I guess. I'm reading it for the second time! But I mean, when you're faced with a decision, you kind of do tend to look ahead. I'm always torn though between this optimism v realism v pessimism.
I think: am I being delusionally optimistic? Or am I being too negative? I can't decide. Of course, it varies day to day!
Thanks again and sending best wishes and good luck your way!
