Meetings are helpful, too, because you and others get to share your "experience, strength and hope" with each other. Meetings are to discuss the program and how it can be applied to life. Often other perspectives can be very helpful with that. They also help us to feel not alone, as we are with others dealing with similar issues.
But individual problem-solving is best done with a sponsor. I guess that's the best way to explain it. Sponsorship and step work is the intensive work, but the meetings can be awesome, as well.
