I haven't chosen one of my talents in the traditional sense, but have journaled about something I take care to do that affects my friends & family.
I'm always careful to let my friends and family know just how much I appreciate their cards & gifts. Not only when they are given, but when I come to use them too. Accepting gifts without guilt doesn't come easily to me, but a gracious acceptance makes such a difference to the person who has given the gift, knowing that their thought & effort is very much appreciated. My joy becomes their joy & my guilt eases, know that the gifts were given in the spirit of love.
