Fear is what makes it hard to wait. The more afraid we are, the harder waiting becomes. Fearful people want to get away from where they are. When we can't flee, a common reaction is to fight.
But waiting is part of movement from something to something more. If you are between opportunities, you are still somewhere... you're "between".
While waiting, we should live actively in the moment. Experience God where you are now. Embrace the present moment as the place you're meant to be.
Seed has been planted, something has begun. Fulfillment of God's promises will come if we cultivate and fertilize what he has sown. That is active waiting.
