"Success doesn't come from day to night, success takes years of hard work and effort."-Jose Diaz 

What this mean is that working hard one day doesn't make you successful. You have to work hard everyday of your life and day by day you will become successful. Little by little if you choose the right and always work hard. If you choose to put in hard work you will receive success. The amount of hard work you put in the amount of success you will receive in return. If you choose to not to work hard then you will receive no success in return.
