The man or woman who desires to go far in life must have a vision else the person will be wandering in the valley of frustration and set back in life.
Show me a man of vision and I will show you a great destiny
Those with vision in life are focused because they have what they are aiming at and they are going in direction of that vision. Those with vision are hardly distracted but that is only on the ground that they don't share their vision in life with everyone they meet.
Vision is a light at the top of dark hill and not everyone will agree to the possibility of such visions being achieved because they are not seeing any path leading to that light on the hill.
I have learnt to speak less of my visions and aspirations in life to everyone because not everyone can and will ever understand my vision in life. My vision is unique to me and it takes men and women of understanding to really know what I am going after and then they become a source of inspiration to help me on the path of achieving my vision in life.
Again, on the path to achieving your vision in life, you have to be prepared for discouraging times and persons who are ready to give you reasons why you should give up on your visions in life. But you got to pay less attention to them because what is driving you is different from what is driving and the reason is because you are not going in the same direction in life like them.
So keep moving until you get to your destination in life and you will be glad you were focused on your vision in life and not the distraction you met on your way to destiny.
