Make it fun
Nobody enjoys injecting effort into something that they don't relish. I'd be sorry for you if you were one of the people who are stuck doing something they inherently don't enjoy, but the point is that even in activities we revel in, light moments are always welcome. Create an atmosphere around that is light, humorous and fun.
Acknowledge your role as the team leader...
and make sure that you always give out positive vibes and stay optimistic. Don't let your negative thoughts rub off on the team and get you all down.
Welcome criticism, but know where to draw the line
Be open to ideas from people who might not be authorized or asked to help. Genuinely consider ideas that may turn out to be for the greater good. Nevertheless, know that you'll have to put your foot down at some point and take decisions that not everyone will appreciate. The director may be "only just a director" but in the end it is her call.
You're never too prepared
No matter how far the big day seems, you never have too much time to prepare. Stay focused, do not be delinquent, and work hard.
Trust spontaneity
Preparation sometimes comes in the way of excellence. True, you can never be too prepared, but the line has to drawn somewhere. Put in a sincere effort; and leave the rest to the D-day eustress.
You'll have to surrender control at some point
No matter what, your duty will be over at some stage, where you have to have faith, trust your cast and crew, and God, and hope everything works out well. And guess what--if you've put in an honest effort, it will! Loosen up!
Look for the positives
During the performance, keep track of all the positives. (The goof-ups won't need conscious tracking. :P) And once it's over, congratulate yourself and your team on the good work. When you start working on the next performance, be sure to use the feedback constructively.
Thank you, Lovneet, for being the in/direct source of wisdom.
