Since no man has a predetermined destiny, every day all man can create a new destiny for himself!

In winter, play with the snow; in summer, play with the Sun! Do not wait for something to come; everything is already here! In autumn, play with the leaves, in spring, play with the flowers! In summer, don't wait for the winter; in winter, don't wait for the summer! Everything is already here, in this present time you live in!
