One small thing

If the project or task seems overwhelming:  Focus on what you CAN do.

Is the whole closet too daunting?
  Just sort one shelf.
The kitchen counter piled high?
  Just fill and run the dishwasher.
A mountain of unopened mail?
  Just toss the junk mail.
A pile of dirty clothes on the chair?
  Just run one load.

Try for small wins.
One step in the direction you want to go.
A single action is movement.  
Movement creates momentum.

Change happens one decision, one action at a time.
You don’t have to do it all today.
You just need to start.

Find one thing you can do.
Do that one thing.
