In every aspect of life, long-term relationships are more rewarding for all parts involved than short-term alliances. Of course, the latter can make useful strategies at key moments and for achieving immediate goals. However, if you are running a marathon and not just trying to win a race, you definitely want reliable partners you can actually count on along the way. Therefore, if you are looking to building your company up in the future, you should see long-term collaboration as a priority.
