“Love is… Something like the clouds that were in the sky before the sun came out. You cannot touch the clouds, you know… but you feel the rain and know how glad the flowers and the thirsty earth are to have it after a hot day. You cannot touch love either… But you feel the sweetness that it pours into everything.”
Keep on beginning and failing. Each time you fail, start all over gain, and you will grow stronger until have accomplished a purpose - not the one you began with perhaps, but one you'll be glad to remember.
