Philosophizing about growing pangs/pains

I like growing. I crave it. I'm excited by new possibilities. I jump head first into them. Sometimes, however, new experiences lead to new introspection which leads to insights that may or may not be so positive.
What do people do once they realize that, through the process of their own experiences and introspection, that they have lead themselves to a point of view which is no longer copasetic with their current state of being?
In other words, is a bird in the hand really worth two in the bush? Am I sacrificing what I know I want for something I think is better for now?
Is this new possibility too new? Am I ready for it? Have other people felt this way in their lives? How often? And what do they do about it?
