One near and dear to my heart.
"A journey of a thousand miles starts with a single step".
Now you need to really think about the meaning and how it can help you in real life. For example, after I had a quadruple heart by pass following years of degradation in fitness due to atherosclerosis I returned home in very bad shape. The following day I started on my back step and I did 5 steps before I was a quivering wreck. The next day I did 6. 6 months later I was no longer counting steps just stopping after 2 hours of continuous step ups. I generally take from that proverb that I can break down huge, sometimes almost insurmountable looking problems, into small chunks that with application I can resolve.
Unfortunately , that was pre RA, and the only proverb that helps with that is 'be prepared to accept what you cannot change". Fortunately, RA does not affect the joints that enable you to smile. 😄
