If you want to be a successful manager, you have to like, and be able to motivate people. It is a truth that a team can do more than any one gifted individual. Picking the right team is the secret.
One thing I have learned from years in business is that recruitment is a key component of business success. Look for personalities that will work on your team. You can teach skills, but you can't change someones personality. Nothing destroys team morale more than having a primadonna or a non team player come into the team.
Choose your staff wisely, nurture them, play to their respective strengths within a high performing team and you will achieve success.
