"Hound" at bay and ideas to live by

I've been able to keep at bay the hound of depression by focusing on what I love - my family and reading - and I've made it through another week, telling myself I have Saturday to rest and Sunday to celebrate my daughter's birthday. The trip to the beach and the birthday party was worth the 5 day 'hardship slog' at school.
Found an old whiteboard of mine under an old bed at my mum's place and on it I had scribbled some wise sayings. Here they are:
1. A vision without the ability to execute, is probably a hallucination - Stephen M. Case (Reader's Digest, 2003)
2. Failure is the price you pay for success.
3. If you don't know what you want to be(come), your objective (in life) is to be a NOBODY.
4. Without a clear picture of how you wish your life to be, how on earth can you begin to live it?
I guess these kind of sayings catch my attention, I believe them and to a certain degree work hard to follow them.
