Stop building teams and start growing teams
Building teams implies that you get the pieces and bolt them together then voila you have a team. Reality is a lot more complex and organic, much like growing an orchid. It takes time, dedication and nurturing. You need to get to know the individuals in the team and learn what motivates them. You need to apply methods to develop team cohesion. You need to develop a team culture. You need to provide the right guidance and direction in a way that is meaningful to the team.
