Money is important in life because it ultimately decides your status, your stability, and what your future will look like. It is especially in high demand right now, and many people just can't make enough to sustain themselves and their families, resulting in the growing homeless crisis and in many families needing financial aid and help from other people to survive. People try to get so much of it and no one even thinks to care about trees being cut down, when it comes to their life. People just want to be able to live without piling debts and stress in regards to money and stability in life.
It is important to let others know about your accomplishments, however, you do not want to be looking for a reward in it. Also you don't want to seem like you want to be better than everyone else. Even if you are :) So agree!
