Being micromanaged undermines your leadership ability. If you have a problem with your boss's approach, ask them for a meeting. Present your concerns in a calm, rational way. Give specific examples of how their behaviour has undermined your performance. If you can't make a dent, start looking for another position. It may be better for you to run your own business. Once you can call the shots, you'll achieve a level of success you never dreamed possible. Continue to trust your instincts.
