What an interesting question!  And it's not until you stop and think about it (well, for me, anyway) that you realise how many good things you have in your life to be thankful for.

For me, today, uppermost, it's that the sun is shining (a blessing and a rare treat in the UK this summer) and I have a great boss.

There's a whole host of other things but that's top right at this moment.
