You can only fight as long as your motivation will let you

Your motivation has to come from within you.  It can't be bought, it can't be taught and it can't be faked.  Many people underestimate the level of effort it takes to win a battle and over time a war.  To finish a battle requires courage, perseverance and commitment.  You've got to be committed to your goal or you won't be successful.  And if you're not willing to prepare, you'll never succeed.

Battling like a true warrior is one activity that gives you what you put into it.   Warriors willing to train and study their progress will discover that the battles they face can be an adventure that provides them much more pleasure than pain.
