We have to commit to the vision over everything else. Indeed, anything that gets in the way of working out the vision is most likely a distraction.
Distraction, as in distant attraction, designed to take away focus from where it really matters and on to things that do not really matter in the long run. We all need to develop that critical skill to be able to distinguish between things that are urgent and things that are truly important.
Everyday, a lot of people and issues will jostle for your limited time and attention, and you will find yourself side tracked every now and then. This is inevitable, a real vision does not manifest overnight, it will take some significant chunk of time investment for which there are no quick returns.
Fulfilling a vision requires 100% commitment, we must be completely focused if we will be able to get it done.
