When we cut a cake in our family, every member has a share in it. Suppose there are four family members in a family. The cake will be cut in four parts comprising the share of each member. When the first member is having his piece, others may be apprehensive that if he has more than our share would be reduced.
Dear friends but our life is not a cake. Even if some one else is having more that does not mean that our share will be reduced. Even person gets his share of luck based on his hard work, expertise, talent, sincerity and actions. Some one else is having more than you does not mean that you will receive less. So do not envy and enjoy your share thanking the Almighty.
