This transit requires patience, tactics, and a more subtle approach to succeed. Your instinct will be to go in with all guns blazing, but this approach will only bring increased resistance and opposition.
While you may need to tone down your ego and level of aggression, you still need to be direct in asserting yourself. Underhand tactics like trickery or passive-aggressiveness will not work for you. Just as arguments and anger from others will let you know you are approaching things the wrong way, so will increased irritability, anger or jealousy on your part.
