Teams exist to accomplish more than anyone person could do alone.
It’s really that simple!
If you could do it all on your own, there would be no need for others to help. If you had all the expertise, skills, and TIME you needed, then there’s no need to involve anyone else.
But when is that the case?
Once you are clear about what it is you want to accomplish, find others that share the same passion for the goal, but have skills that compliment yours.
