Definiteness of purpose is the starting point of all achievement.
–W. Clement Stone
It is very important to have a clear vision and a definiteness in purpose before anything meaningful is conceived by the human mind. Because then only one can focus with complete head and heart and achieve the intended result. On the contrary, if there are doubts, fears or self pity involved while any action is taken or an effort is made, then the confidence and faith will lack and consequentially the results become uncertain or get affected adversely.
So, we must always think and make the thinking clear at first – have a clear conscience and have a definiteness of purpose which is the starting point of all achievements that’d result out of undoubted and passionate efforts.
