People have a habit of not being satisfied. In truth, there is nothing wrong with being greedy or having many dreams in life, as long as you don't do harm to others to get everything you want. For me, if you are capable of doing something and you know yourself that you can achieve your dreams, there is nothing wrong if we aspire even higher.
Greed exists at any age because a person's dreams are not possible to be fulfilled. If one dream of a person is achieved then he dream for another thing but he never stop thinking about money.
Even people will not say that they have enough money so when they recieve a jackpot they will say that if they find another jackpot then it will be enough but human never become thankful for what they have.
I think if one is hardworkers and is earning by using his skills then his dreams should be higher because the main reason behind his earning is his satisfaction and satisfaction will come if he achieved his dreams one after the other.
