Take wine, a good example. A glass of wine with a meal is something which many people do take some sort of pleasure in, though I suspect the vast majority of people in this day and age simply drink it as many would have once drunk water, milk, or something similar with their meal. To most it seems to be simply something to accompany the meal, nothing in and of itself. To a connoisseur of wine then the wine is possibly the major aspect of the meal, but still they miss something. The wine itself can be savoured and tasted, enjoyed, remembered. The way that the wine may compliment the meal, or not as the case may be, is equally as important and as much pleasure can be taken in that. Each experience can indeed be new, even if it is one you have felt before.
Many times I have walked in the rain, simply out of enjoyment. Today I found myself caught outside without my hat, and I do not yet have an umbrella. Many began to dash for the nearest shelter, hurrying along, suddenly desperate to be elsewhere, out of this meteorological phenomena which they have decided is unpleasant. It was cold, chill throughout and I was near-shivering already, but I did not, and still do not, believe that hurrying to escape this, joining the mad rush for crowded shelter, would in any way benefit my health. Instead I paused for a moment, tilting my head back and letting the rain strike my face, damping my hair and trickling down my neck. The fact that it could be considered a pleasant or unpleasant experience was not something I was interested in at that time. Merely that it was an experience, a sensation that I have experienced before and probably will again but never in quite the same way.
Living in the moment implies an impetuousness. Seize the moment, grab the now, worry nothing for the past or the future, simply live now. I oppose this most strongly. The past makes us who we are, the tragedies and traumas of it combine to become the aspects of our personality. There is nothing to be ashamed of in the past, though I would not relate certain events to various people for reasons that only I need to know, but the past is gone. If you hold on to what is slipping away, you will be trapped by it, but if you let it go completely then you have nothing from before. Have no regrets for what is gone, no matter what it may be. Mourn when appropriate, and then smile and laugh afterwards. There are times when we feel sad and we should indulge ourselves in those moments, but we should not draw them out any longer than we have to.
No more should we artificially try to extend moments of joy and happiness, pleasant though they may be. Our minds themselves know when the moments are past and trying to force them to remain will simply seperate us from the world.
I suppose that is the main point. Do not live in the past. Do not live in the future. Do not live in the present. Live, be, experience. Sorrow, joy, guilt, freedom, hatred, love, pleasure, pain, accept all of them simply for what they are, and neither expect nor try to make them or yourself anything more. Certainly try and change things, advance yourself if you wish, sink if you wish, but do it for yourself rather than because you feel you should. What matters is what you want, what you think is right, not what others tell you or what you feel should be so.
