Some professionals will view relationship building as a type of choir you are forced to do but with an attitude like this you will likely foster fake friends and meaningless connections. When you do something with someone it is almost always more fun than doing it on your own, right?
You should think of relationship building in the same type of context. It should be a thrill to meet someone new and build a relationship which has the potential to stand the test of time.
Once you find building on your relationships a task, one which you need to get done, you may find yourself a bit insane. Your friends will turn out to be your enemies and your allies will switch teams.
Does this paint an ugly enough picture for you?
This is not an attempt to scare you but rather warn you of future mistakes. Plan accordingly and you will have nothing to worry about!
