Keep your personal life at home - A good employee can separate work from home. It shows that you dedicate all your time to work when you're in the office.

Always be happy and positive - Smiling is contagious. It's not only good for you but also keep up the spirit of the whole team.

Be on time -- Nobody likes waiting for others.

Don't ask questions that you can answer yourself -- Your boss may get hundreds of questions a day. Don't show him that you're lazy to think!

Take responsibility for what you've done -- Excuses usually make you look weak. Try to impress your boss with what you've learned, and admit your mistakes, rather than making excuses for what you've done wrong.

Find solutions, not problems -- Try to spend some time to find possible solutions. Your boss will be impressed when you go to him with a problem AND suggest a solution.

Don't get too emotional -- If you're angry or upset, don't make a call or send email at that time. Try to calm down and respond calmly. Your boss will admire your diplomacy.

Be proactive -- It won't do any good if you come up with a list of good ideas and then never follow up on them. Try to pick a few best ideas and follow through with them.

Ask for and give feedback -- Communication is very important. If you like something that your boss has done, let him know. Vice versa, try to get his feedback so that you can learn from it.

Stop complaining -- Don't make your team down because of your complaining. It won't solve anything. Direct the problem to appropriate member and try to solve that problem.
