Do it and see. Air is basically logical, creating abstract conceptual systems, maps and models of ideas. Of course, what is considered logical depends on one's premises, so unless these are initially grounded in the practical earth, we can create castles in the air. Earth and water want to protect, so they are normally more serious. Earth may save for practical reasons, because something could be useful.
Water wants emotional security.
This may simply be personal security or may include others. The water instinct is to hold on and to hold in. Fire and air want to move on. At the water or subconscious level, life is connected, so water is a key to psychic ability. When water factors are combined with fire or earth factors, individuals tend to act on the inner psychic awareness, but they may not be conscious of why they are doing what they are doing and often the action is just carrying out personal habits.
