"The battles that count aren't the ones for gold medals. The struggles within yourself--the invisible, inevitable battles inside all of us--that's where it's at." - Jesse Owens
The inner battle is disciplining yourself isn't it? Battling your emotions, your thoughts, your fears.... working through them to come out the victor.
The lady who turns down the bread basket at a restaurant, all the while loving bread incredibly, the man who did not raise his voice for the first time when talking to his children, the teenager who resists peer pressure to drink alcholol..... won an incredible, invisible, battle.
Most of our inner battles can be won. Imagine if we won the ones we could.... how strong would we be? We could take on the world, change the world, perhaps move mountains....
