How to Live Magically Every Day
If someone else is doing it to you, all your magic is going to be old victim magic and you are going to have to wait until they decide to stop for you to have what you want. You might be waiting for a very long time. So you can't pretend to be some kind of stupid "muggle." Muggle, as in the non-wizard term in the Harry Potter series.
The third requirement is that you have to be comfortable with change because change is what enables you to have magic. People are usually afraid of change because the general consensus is that change is stressful. Change is hard. That's because for all of us, when we were young, whenever big stresses happened to us, like moving to another place where we didn't have any friends, or when something bad happened; like losing a parent, everything would change and life would never be the same. The good thing is that there are no external things that you have to do. It's all internal. It's all about being willing to stop resisting change and being willing to see new possibilities.
