They say that if you are depressed you are living in the past, if you are anxious you are living in the future but if you are at peace then you are living in the now.
It sums my experiences up to a tee.
For years I was depressed about the past and anxious about the future. Always worrying about what I might have said or done and then worrying about how I would deal with these things when the time came. I never lived in the now with any kind of peace, I was always aware of too much other stuff going on and never gave myself a chance of witnessing what was happening at that moment.
Today however, I very seldom worry about the past and am learning to let the future unfold as each day comes and I meet it with renewed passion and vigour. We none of us know what the future brings. There are challenges that we must face and there are good times that we must enjoy but nothing is set in stone.
