The reason why it is important to really know what you want is so that when opportunities come your way, because you better believe they will especially if you are working hard and being excellent, you are better positioned to weather this bout of doubts. So if you are still unsure of what that is, give yourself time to figure it out. And once you do, write it down and revisit it everyday, twice to make it stick. So whenever an opportunity comes your way, look it through that lens. Is it align with what you want? If so, by all means grab it with both hands. If not, take comfort that you are in this to win it.
