Those who do not want to imitate anything, produce nothing
I find that the best way to learn more about yourself, is through imitation. Imitate someone you look up to. Learn the traits you want for yourself. Imitate someone you don't feel you connect to by finding what you do connect over through that imitation.
This can apply to so many aspects of a person's life; emotional (personalities, traits, ), or physical (habits, style, etc), or even their expressions through art (painting, drawing, photography, etc)
In modeling for example, when it comes to posing, I like to study the poses that I see people I admire doing. And not just the poses, but their faces, expressions, and the feeling they exude on a whole to give that image a specific tone. If you copy what you admire, you then have a chance to add your own interpretation to it, and create something new from that which inspired you.
People seem to have this fear of not wanting to copy anyone else...of wanting to do something unique and individual. But the saying that nothing is original holds true-to a point. For example, yes, there are millions of pictures of models doing the "Rosie the Riveter" pose and look (including myself). But each person who emulates her for their picture is different. Each person has their own style that they express, even when wearing the "same clothing" (or close enough to it), with the same hairstyle and makeup. Because even if a million girls have posed as Rosie, YOU haven't yet, and when you do, it's unique because its you doing it (currently trying to shoo away the "you are not a beautiful or unique snowflake" quote that pops in my head every time I even SAY the word unique...).
To summarize, my advice is simply this: imitate and study what you admire, so you can learn, and grow from it and become closer to the person you want to be.
