For when I get up 'on the wrong side of the bed'; or don't want to get up at all: "Fake it until you make it". Act as if you have energy and enthusiasm - until you do! Works every time!
For those 'Ahah' lightbulb moments (I think, from Conversations with God): "You don't know what you don't know until not knowing doesn't serve you anymore". We only get what we can handle; when we can handle it. So I tend to have my eyes and ears open all the time (and learnt to keep my mouth shut!) . You never know who you're gonna meet; or what you're gonna learn!
