I really try to live one day at a time and not only when it comes to drinking.
If I have a lazy Saturday and get nothing done I may feel that I was a little too lazy that day and I should have done more but I don't let that dictate my Sunday. Sunday is day one again. I don't play catch up for my lazy Saturday but I also don't use it as en excuse to be lazy again. I play each day as it comes.
Having said that I drank for 26 years and that time seemed to fly by when I look back now. Not drinking for 26 years does not seem so daunting to me. I only have this one life and it is time to live it. I wasted much of the first half, I will be damned if I waste the second half.
