Knowing yourself is step one. Step two is going after what you want.
Bring agendas to your 1-1s when you have things you need to talk about. When you want to work on projects, ask. Advocate for yourself. When your manager isn’t helpful, look for other places to get help. Seek out feedback, including constructive feedback on areas to improve. When that feedback comes to you, take it graciously, even when you don’t agree with it.
When you are persistently unhappy, say something. When you are stuck, ask for help. When you want a raise, ask for it. When you want a promotion, find out what you need to do to get it.
Your manager cannot force work–life balance on you. If you want to go home, figure out how to get your work done and go home. Sometimes you will have to go against the cultural grain to set your own boundaries, and that will feel uncomfortable. On the flip side, sometimes if you want a bigger job, you will have to work more hours to get it.
You will not get everything you ask for, and asking is not usually a fun or comfortable experience. However, it’s the fastest way forward. If your manager is conscientious, he’ll appreciate your candor. He may not be conscientious, or he may like you less for asking, and then you’ll know that about your current situation. I can’t guarantee you that it’ll go well, but if you’ve set a goal for yourself, you owe it to yourself to do what you can to make it happen.
