Living in the now

Well, suddenly everything seems different somehow for me right now.
Had been reading some books as usual, when suddenly a couple of opinions about life in genereal surfaced through me. The fact is that not so much as a opinion, it's simply that I prefer to live my life that way.
The first thing, is that I think that life would be better if we could always live in the NOW. Well always planning ahead and thinking about the past is going to get us nowhere,after all the beauty of a ride is missed if we looked at the smoke coming from the back or the road in the front, it's in admiring the ride from within the car and looking all around you.
Then, I have suddenly grown up -say that the past no longer threatens me and presto! suddenly there is this feeling I'm happy but which suddenly goes out again, maybe the day It stays for longer is the day to rejoice.
