A small step can make a big difference.

Just like a big sin begins with a small step in the wrong direction,

a small step in the right direction can bring major Teshuvah.

Koneh Olam b'shaah echas- We can acquire worlds in one hour- can also mean that in one second of turning aside from the wrong thing we can acquire worlds.

heard from a Shiur by Rebbetzin Kalmonovitz
