Wolves are pack animals. A lone wolf quickly dies because only with the support of a unified pack can they bring down animals with which to feed themselves.
Likewise, the lone wolf in an organization may have some limited success but it will be the exception rather than a consistent pattern.
You need your own wolf pack within and outside the organization. Who do you rely on? Who can help you to get things done, to get that new product or campaign out the door? Extend this to external providers as well. The more useful people with whom you have relationships the better you’ll able to put together a team that cannot be beat.
And always remember that it should be a reciprocal relationship. No pack will have you long if you only take from others. Be generous with your assistance, advice and aid when needed.
