Your high-flying ideas are great at motivating people and keeping you feeling hopeful, but they might be a bit too unrealistic to come to fruition: and that could ultimately be quite disappointing. To save yourself from a harsh reality check, be more grounded about your chances for success in a new venture. It's not that you will fail necessarily, but you can't assume you'll be victorious. Do yourself a favor and think up a backup plan just in case.
