Do you like well thought out plans and steady-paced work or do you thrive under pressure? Do you work best in the morning or at night? Think more about what makes you tick, make a list of those things, and incorporate them into your ways of working.
A big part of being effective at work is being a good communicator. Pay attention, give eye contact, really listen, ask open-ended questions and don't interrupt people (or be on your device!) when someone is talking to you — these things can be absolutely game-changing.
