Be yourself. Everyone else is already taken.” –Oscar Wilde
The problem with trying to be somebody else is it simply can’t be done.
Sure, you can learn from them, you might be able to imitate things you see, but in the end you’ll never be them. And they’ll never be you. And any attempt to do so is going to fall short.
Each of us has a unique blend of skills, personality, and experience. Which means we each bring to the table things that no one else can.
You’re the only one who can be you, so you might as well be the best you you can be. No one else can even come close.
