Inauthentic is probably the thing I’d least like for people to say about me. A hellacious master of BS; OK. A journeyman rather than a master? I’m OK with that also because I move around to so many things. So neither of those things bothers me.
Being authentic for me is all about doing lots of different things and exploring. And yes, I know that being a sort of grab-bag person makes people who only do one thing uncomfortable. In their lights, mastery of “the one thing” is everything. And I’m OK with that, too. Just as long as they don’t try to get too damn stuffy about their perfection.
Having multiple interests is an insurance policy against boredom and the vicissitudes of life. Can’t pursue one passion, you can start working on the other.
No one can call you inauthentic, you won’t be bored, and you may always be able to make a dollar too.
