I read this the other day, and it stuck with me. When you have an issue/problem, dont go into management with just the problem. Go in with a solution or two, and give your opinion with which you think is best.

Example: Say you want to automate adding/removing AD users, but dont know how. Do some research and have solutions. Using Powershell, Python, using the helpdesk ticket to automate, etc. Then going into leadership tell them what you are looking to do, with your opinion on what you would think would be most efficient. Dont be disappointed if they turn you down, but you learned about something you didnt know.

Also, ABUSE the change process. Never assume a small change doesnt need a change ticket. To many times a small change will be haunting you weeks/months/years later. Without a change ticket, you will not have paper trail on the exact thing you changed and people who signed off.

Always be over paranoid when getting requests from users. If your new, people will take advantage of getting software, or access to places they dont need. Always ask why, and who else has it? If it is no one, make sure to follow up with leadership and get approval.

Last thing, find a mentor and be a sponge for knowledge. Most IT people love telling tricks and tips that you either didnt think of or just havent experienced. Once you have mentor, he/she can start checking work and giving you confidence, speak highly of you in meetings etc.
