The fact that we live once and the fact that if you work hard you get benefits such things motivate me to work hard and never give up.
Indeed money isn't everything in life but it is very helping and it is effective after all with money you can even get healed from a disease or go for a nice vacation with friends it's needed and it's worth working hard for it.
A lot of people keep making this statement that money is not everything in life but in reality money is actually almost everything in life. There is nothing you can do in this life without money. In fact, you cannot be alive today without money because money is what you're going to use to buy food that you're going to eat and when you don't eat, you are most likely going to die of hunger.
