Let me not allow myself to sink in a sin

Knowing the wisdom and acquiring it is not a easy tasks for me. I do not have "Eureka" moment. Every day is a learning. If I move a feet ahead, I slip a meter behind. If I grow a feet, I fall a meter. Human greed are inherited, fueled by environment, developed by own desires. I am responsible for my success or failures. I will not give up. I will keep on fighting with my own flesh and taste the wisdom before I die. By the way, what is sin?
