In Isolation & with Other People
The individual in his or her environment, be it at work or home will find that being alone is a fact of life. Such times can be a source of great strength and may give an opportunity to reflect and order thoughts. To be sure of one's thoughts and actions, reconciliation between reality and the ideal will need to be meditated upon.
Socially, having an assertive personality will mean that one is able to state one' s case succinctly and ensure that the concept one is proposing is readily understood. In the absence of aggression one will never force an issue, but consider reasoned argument at a later date.
Don't carry the world on your shoulders!
