Believe it or not, they used to build bridges by first flying a kite from one side of the river or gorge to the other. Someone on the opposite side caught the kite and tied a little thicker, stronger string to the end of the kite string, and the men who had sent the kite over pulled the new, thicker string back across. The teams on each side kept repeating the process, next with an even stronger string, then a cord, then a thin rope, then a thicker rope, and so on. Eventually they could pull a small steel cable across, then a heavier one, until finally they had a cable across the expanse that was strong enough to support them and their tools and materials.—And it all started with one tiny kite string!
That’s how habits are formed, both good and bad. Add a thread every day, and before long you can’t break it. Start developing a good habit by taking the first step, however small, in the right direction. Then keep at it until you’ve built up a routine that can’t easily be broken.
