Two aspects to adjustment: internal (within self) and external (with surroundings/community).
Internal adjustment is more important - and consists in the absence of internal contradictions and difficulties arising from one's own temperament, choices, values, thoughts, etc. Without internal adjustment it is impossible to be happy with one's life.
External adjustment consists in being able to interract with one's environment and community in a positive way (whatever promotes peace, happiness and positive utility).
Internal/External contradiction. There may arise occasion when circumstances are such that the requirements for internal and external adjustment are contradictory. (If you enjoy quiet and stillness because it helps you think, but you are surrounded by noise and distraction). In such cases either:
1. Move away from your surroundings;
2. Try to change your internal disposition - which is near impossible;
3. Try to change your environment (ie. prepare for diplomacy or war).
