the artifact of brain reform

Look to it that way, a cube of material; the same as your origin, family and values. This is what your brain is, when you are a newly checked-in guest to this life. Using the tools, from events you survive, to entities you encounter, you shape that cube into a key that opens the life door you've decided you wanted most. Keys don't live long if they are left to rust, and isolating keys ain't the answer. Isolation causes the key-hole to be wider or narrower for the key to fit-in.
The air that rusts the key is the everyday events that drives you away from your goal. The key-hole is the right choice you have to make in order to open your goals door.
