It Is Difficult For A Single Manager To Manage Companies Through The Entire Life Cycle Of A Company!! ─ Law #39
Managers have difficulty working in all the vastly different environments of start-ups, growing companies, stable companies, and companies in downturn cycles.
Personalities have a greater effect on the performances of a manager than do training and experience in handling different situations.
For example, an entrepreneur would probably be bored in a care-taking situation, and a caretaker would probably be frightened of the risk-taking required of a growth situation.
