Focus is within your control, but what if the people around you see things through a different lenses? Will you lose your vision? People can only derail you by that much, but if the majority of your circle of influence is completely off with what you are trying to achieve, the chances of persisting with your vision become lower and lower. Focus not only on your goal, but make sure that the people you are sharing your views with don’t have leverage on you. Stay truthful to who you are.
