Lyk,

I had worked 20 years in IT/Datacom/Telecom world.  As far as I can remember, I always have too much to do, too little time to do it and I never know enough.  So, what you are facing is highly normal in an IT world.

Learn to say no.

You are just a pawn.  Why the hell you need to act like a big boss and take on all the responsibility?? You have a boss.  Do not say yes or no.  Just Tai Chi the decision to your boss.  If someone ask you to do something, ask the person to talk to your boss first.  Just say you are a pawn and you need to follow order.  Ask your boss to prioritize the things that you should do.  If he/she does not, then, you prioritze your own list.  If someone want you to do something fast and drop what you are doing now,  tell the person to talk to your boss.  Let your boss make the decision.  You have a boss.  Use it.  Let your boss be the bad guy.  It is his/her job to make this kind of decision.

This is the kind of soft skill that a fresh grad need to learn fast.

Lyk,

You are not the boss.  Do not take on the responsibility of being a boss.  You tell your boss that you need a server to try out before implementing something.  If your boss say it is okay to try out on the production  server, then, you go ahead..  It is not your responsibility then.  Let your boss make the tough decision.  You can only propose and suggest alternative.  It is up to your boss to make the decision. 

IT IS NOT YOUR JOB!!!

Learn how to let your boss make the decision.
