Give 100%

Today I learned this line. Before that I was not knowing its meaning.After very deep though I could digest it. According to me give 100% means 'present all what you have,without any wastage'.For example We know that our enemy has 80% power while we have only 50% What to do? At that time we will have to utilise our 100% full power out of our 50%. And believe me You will be extra ordinary. If enemy wastes his power then his power will be reduced up to 50% spontaneously. So that keep your morel high to achieve your goal
