Living my today to the full

Life is full of suprises. There are moments when I hear a dark voice telling me to regret something of the past, that "if only" refrain.
Well, I cannot change the past anymore. I can, however, honor it by learning the lessons it wants to teach me.
But I have my today to live to the full. This is the only moment I have in my hands.
It is useless to daydream about tomorrow.
I will focus on the present moment.
I will not expect anything.
I will be grateful.
I will love.
