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.
Having more dreams and higher aspirations is not part of being greedy, because these two things are part of a person's ability to make them happen. Even though other people may see and judge this as a sign of dissatisfaction with someone, basically it can be quite good for someone who wants to change their life to become richer and more financially stable.
Because greed and high dreams are actually different and will never be the same for both of them, as well as high ideals which are really required for everyone to have so that everyone is willing to work hard and not complain about any conditions in their life. Greed is a bad part when someone starts not wanting to be grateful for what he has gotten so far even though this is also caused by his dissatisfaction with something. But goals and dreams must be achieved through effort so that they can be obtained because basically both will never come without being picked up through effort.
