I have found that just focusing on being grateful makes me more giving. Finding small things to be thankful for creates a mindset of abundance. Where there is abundance, giving is not just easy but natural. Here is an example of how my perspective has shifted.
When I was younger, like many 'kids' Christmas was about what I got . . . sometime, not that many years ago something rather strange happened. I got 'full' of stuff. . . I stopped really caring about what I got (although on the rare occasion someone truly *got* me and found something -- often a small thing -- that really spoke to me, well those times are really gold.) Anyway, my greatest joy during the holiday season is giving to others - - the family our office 'adopts', the annual toy drive and, more personally, our family tradition of baking goodies and delivering them to neighbours' doorsteps on Christmas Eve. Yes, that is what the season is for me.
So, I say GIVE in unexpected ways . . . and more than giving THINGS, give smiles, kindness and prayers for everyone who crosses your path. They are there for a reason.
