Focus.
In today's world it is definitely difficult to stay focused on one task. Just today I was distracted from finishing cleaning up my room by the scandalous Olivia Pope. The news, new friends, old friends; these can all leave you questioning where you stand. But the most important thing to do is to have faith that as long as you focus on that one task and make it your duty to follow through, you'll overcome all the worrying and be able to reap all the benefits. Focusing doesn't just mean "paying attention to" it means allowing yourself to conquer adversity, to jump over hurdles, to effortlessly plan for the future in order for you to accomplish the goal that you're working toward.
