For the small things in life, follow the advice in one of Swami’s books: Do It NOW! Don’t leave dirty dishes in the sink. Try answering all your emails before going to bed. You’ll be amazed at how much freer your mind will feel.
For larger tasks, don’t let them languish on a shelf. Leaving something unfinished is like leaving a faucet dripping: It drains your energy. I’ve had this lesson brought home to me recently.
