This is the main outline. As each module is approached, you can break it down further. If you look at a large indigestable problem as something that can be broken down into small enough pieces to be eaten, then you'll be able to approach something that seems impossible, and have it all fall into place.

This process only improves with practice, so KEEP TRYING.
