I stumbled onto one several years ago that was stuck on my refrigerator door for months and will always be stuck in my mind. First - something to do. Second - something to look forward to. Third - someone to love. Something to do.
Work is a beautiful four-letter word.
To achieve, to change things, to add value - these are high callings. A life spent in idleness is a tragedy. Improving the lot of just one person improves the human condition. Something to look forward to. Your hopes and dreams are the embryos of your future happiness - or lack of it.
