Often your co-workers (especially those who’ve been at that same job longer than you), will know how to do certain specific things that you don’t know. Trying to figure out those things by yourself might take hours or days, where as if you ask them it might take minutes!

Sometimes, you don’t know who to contact, well contact someone and ask them who you can contact regarding x.

The point is, you are in a team. You have people as resources. Use them. People are glad to help! When you use your co-workers as resources, and you get good at finding contacts and asking them, and glueing peoples knowledge together, you can potentially save a lot of time!
