There are a great many teachers we can benefit from. Of those that touch us deeply we like to gather their wisdom by collecting their best books and quotes. These we read and re-read as inspiration comes. I find it very comforting that these individuals have struggled and suffered just as we have but found they could become masters of their destiny just as we can.
So here they are, Einstein, Buddha, John Muir Thic Nhat Hanh, and Winston Churchill. If you don't have a collection of your own this may get you started.
Look for wise and kind people, ones that grab your heart and mind. They
are still with us through these works, ready to take our hand and guide
us onward. Bon Voyage!
