Here are three which I find helpful.
As I began thiis blog and focussed on simplicity I often asked myself when I was unsure of how to proceed What would be simplest? I found that i nearly always knew the answer to this question - then I just had to do it.
The second question is helpful in putting any dilemma into perspective. Is this a life changing decision? More often than not it isn't! You can also put the issue on a scale of 1 - 10 in importance....
The third question is a new one for me. My word for the year is strong and I find myself asking Does this kind of self talk/train of thought/potential action/way of dealing with this make me stronger? I've been finding this really useful.
Do you have any good questions?
