Flow

Stagnant water stinks.
So it is with life. We cannot get hold of an experience, even the best one, and try to put a frame around it and freeze it in time.
"Happily ever after" is a lie. Oops, sorry, it's such a strong term. "Happily ever after" does not mean that from-now-on-everything-is-okay-and-i-can-just-sit-down-and-enjoy. That is why "happily ever after" is only for fairy tales.
Real life is always on the move. As my father likes to say, the only constant thing in life is change.
So I guess the best attitudes that I should have in front of life are gratitude, attention and detachment.
Gratitude, because many things in life, the things that really matter, are freely given to us. What make us most happy are not the things that we have "earned", but those that are freely shared with us out of the goodness of God and of people's hearts.
Attention, because the present moment is the only one that I have and that is in my hands. It is useless to regret the past and to worry about the future. They are not in my hands. I should live well the present because it is the gift that I have. I've read once that the present moment is a gift, that is why it is called "present".
Detachment, because everything passes. Detachment does not mean stoicism. It means accepting that everything that we have is on loan and it is inutile to cling to them.
To live is to flow, like a river.
