Well.. Greed is essential in helping you to reach out more for profit otherwise, you would have settle with your little success. I think striking the balance and maintaining it is what is important as far as greed goes!
Do not be greedy, they will probably kill you at any time, set goals for yourself to achieve a specific goal, so it can be said that in business must have specific goals clearly , so I think we should be strong in learning who to go ahead and ask for their help.
