A single thought

As a single footstep will not make a path on the earth, so a single thought will not make a pathway in the mind. To make a deep physical path, we walk again and again. To make a deep mental path, we must think over and over the kind of thoughts we wish to dominate our lives.

- Wilfred Arlan Peterson, The Art of Living, Day by Day: Three Hundred and Sixty-five Thoughts, Ideas, Ideals, Experiences, Adventures, Inspirations, to Enrich Your Life

Love this quote, which is often misattributed to Henry D. Thoreau. It speaks to the importance of perseverance and patience, both in action and in thought. A single day of meditation has no more impact on the mind than a single day in the gym does on the body. That's not to say it does no good. But to make a deep, significant impact with lasting gains, we have to make the effort consistently and continuously.
