I believe yesterday is an experience, an experience to be improved upon, so that the life we live today can be more convenient. Then we plan for a better tomorrow!
I believe that memory lane is like spare part used to mend today's living and stones used to build a more enduring tomorrow.
I think it is the epicureans that only think of today and neither borders for yesterday, and never thinks of tomorrow. They say, 'let us eat and drink today, for tomorrow we die'.
