The higher your hopes, the farther you could fall if they are not realized. Just be cautious right now and admit that while you want things to go well, you can't ensure that they will. Keep an open mind and be prepared to accept whatever happens. Take each hour as it comes and do not try to control the day. If you do, you will only end up getting frustrated: and probably frustrating other people in the process. Focus on collaboration, not on having total control.
