What CAN you do?

I've liked this quote by Theodore Roosevelt for a long time ... "Do what you can with what you have where you are."

That thought helped carry me through many seasons -

• Finding a spiritual identity outside the boxes of my past
  
• Begin walk/running at age 28 (never exercised before) after the birth of my third son in four and half years.
• Progressing to run a full marathon (26.2 miles) two years later
• Starting and managing a seasonal business for eleven years
  
• Waking up in a hospital in California, finding out I almost died twelve days earlier
  
• Walk again - after the doctors said I might not
  
• Climbing out of the black hole of depression
• On to running again, along with biking
  
• Now I'm hanging tight to that thought - as word by word, I try to write a book.

This morning I was motivated again when I read this in an interview.

People need to stop thinking about what can't be done and start thinking about what CAN? - Gary Vaynerchuk

100 years ago or today - the truth is still the same.
How much time do I (and you) spend focusing on what we can't do rather than on what we can do?
Any area of your life at a standstill until you switch your focus?
