Your essential purpose in life is simply to do something that makes you feel an independent and effective individual. You could be doing this in some form of leadership or selling, or by forcing others to look at themselves in a new way. You could accomplish this either consciously, by carrying out a deliberate act in the name of some cause, or unconsciously, by making it hard for others to relate to you as you are.
You should be consciously aware of your pioneering streak, for in this way not only do you enjoy life more, but you avoid feeling pushed around by others - and with you it's more or less a case of push or be pushed.
This can be objectionable at times - and indeed your childlike impetuosity can repel others' co-operation - but you must have the freedom to act. Don't just think about it and get pent-up in the process. At all costs you need to avoid negative emotions like resentment, regret or self-pity, for they would deny you what is essential to your Arian nature - straightforwardness in responding to a challenge with action.
You should not be afraid to be forceful in this. If you are afraid, then look for negative examples of force in your personal history, what initially compromised your right to assert yourself. This right is like the outpouring of life itself and nothing should be allowed to get in the way of its innocence and freshness for this is what enables your Sign, like no other, to set the ball rolling.
