"now is the most important." - I agree... we can not change the events that have already happened but we can control our future base on our present act. people might see changes and consider you for what is your doing or acting right now and not for what you've done in the past. I mean, for instance, they may set aside their doubt in you (for being a liar) for a while if you start showing your sincerity to them. :)

yeah,i agree with you.now is the most important,the past have gone with the wind and the thing which has been left is regret and remember.we should take the experience to go forward .life is valuable and short.we should wait there to recall what we has done.we should enjoy ourselves without delay.

I do not agree !the time which passed is also very important!
