Let your mind see every detail of your own special version of the very best that life can be. If you could make the world exactly to your liking, consider very specifically just how that world would be. If you could spend your time doing precisely what you wish, how would the moments of your life be lived?
What if you gave someone a gift, and they neglected to thank you for it - would you be likely to give them another? Life is the same way. In order to attract more of the blessings that life has to offer, you must truly appreciate what you already have.
