I just love Amy Poehler, don't you??
I love this quote because what she's basically saying is that self awareness is so important, and I absolutely agree. You have to know yourself. What makes one person happy and works for them may not work for you at all. For example, if you're introverted, you won't like a job that requires you to mix and mingle with people all day long. Part of the reason that I had no idea what I wanted to do in college was because I didn't really know myself.
The other part of what Amy is saying is that when you have a sense of who you are, you will display confidence and peace in yourself. When you don't know who you are, you will be insecure and always feel like you're trying on different hats but none of them fit just right. There is such a liberating peace that comes over you when you finally know who you are and own it. And that vibe will absolutely attract people - the right people - to you.
My advice? Take the Myers-Briggs personality test, which will teach you a lot about yourself, and don't be afraid to try new things. Most importantly, own who you are and don't try to be someone you're not, just to impress people. I hope you like this quote as much as I do. Have a great week! xo
