At this point in my life, I'm not going to spend a lot of time focusing on dissatisfaction with who I am, and I'm not going to spend a lot of time tempering my personality. Whatever job I have next, I'm going to be somebody who wants to get things done.
There will be a moment in life, whether you're forceful or not, where someone will label you something that is negative.
You might as well go through life the way you want to. If what you want is to be engaged and forceful, to 'lean in,' well, do that.
