We have generally noted that some of the families of birds fly in the airs in group form,one in their captain leader and others follow him.Sometimes i have often noted only single bird of family birds member fly in the air solely.He has no leader no captain present to lead him he set himself in the air,he fixes height which require,analyses his direction himself.He is his own adviser and his own master.Forget what his priority to go while joining his family,food shelter etc.
Same sometimes man has to set his strategy,planning oblique himself forget whether is so social person has number of friends alternatives etc.It is rightly said man comes alone in the world and has to go from this world alone.
He keeps single body single mind and single thinking.
If you wanna promote,progress and develop yourself you have to be bird like nature when he is alone and sets his priority himself.He works hard,finds his food with his handwork and struggle.
