In truth the secret of success lies in helping others. Each time we help others, there are two types of rewards that comes to us. These rewards could be physical or spiritual. Spiritual blessing comes from the Almighty and also part of the physical blessing also comes from Him. But let us look at a typical example of a physical reward to solving human problem. Before now communication was made by letter writing, and landline phone, but some persons sat down and came up with the idea on how to solve the problem of humanity by communication faster and cheaper and to today we have facebook, twitter, etc. And in truth this discovery has really rewarded the founders. Help others and heaven will open the door of blessings.
