So many people get wrapped up simply in what they see in plain sight when in reality, a clear vision is much more important. In light of this topic, sight is the ability to see things as they are whereas vision, on the other hand, is being able to see things as they could be.
It's fallacious to think that you can hit a target if you're not aiming directly at it. Your chances of hitting that target by accident are extremely slim. Having a clear vision of where you want to be in the future, what you want to be doing, how you wish to develop as an individual are essential to actually getting there, doing it, and being that person. Think of it this way: If you want to hit a target, you have to be aiming at it. Shooting blindly and expecting the best is a contradiction that will likely end in disappointment.
The same is true in life. If you want to hit a target, you have to have something to aim for. Clear goals are a result of a clear vision. Not everyone has a vision for what they wish to attain in their future. Most people get stuck in a routine that usually has nothing to do with where they want to be. This is usually the result of a lack of vision.
Another reason a clear vision is important is due to the fact that what you see around you in plain sight can deter you from aiming for a better future if you lack the vision to see beyond your current circumstances. A young basketball player who lives in poverty may eventually give up on his or her dream to become a professional basketball player if they lack the vision to see beyond their current situation. But with a clear vision that places them in their desired league, they have a much better chance of reaching that goal.
My challenge to you is to move forward with a purpose. Don't go through this life aimlessly, simply hoping for the best and taking actions that have nothing to do with a brighter future. Have a clear vision, trust in it, and see yourself beyond your present circumstances.
