The more useful type of tension can be as magical as the tug of a helium balloon on the string in a child’s hand. It can also be equally difficult to control and similarly capable of escape. It can also be as dynamic as launching from a trampoline. Learning to use it properly takes practice, but the results can be pretty impressive. This is the tension that effectively links pay and performance. It is also the tension that links groups, and entire companies, together into a stronger, more cohesive entity.
