The best management style is one based upon three concepts:
Clear, rational, positive.
Clear means, Clear goals and values that are clearly communicated to everyone who needs to know.
Rational means, NEVER treating anyone unreasonably; having a reason for everything you do; acting according to rational plans that are capable of achieving the goals you set at point one.
Positive means: positive mental attitude, especially during tough times, and having only positive intentions to add value to everyone you meet.
