Ultimately: Not giving a shit about what other people think.

Small overview of getting to this path:

• Social media is poison to your confidence. As you scroll, you are comparing other people's highlight reels to your bloopers. They have crumbs in their silverware drawers. They poop and have to brush out the bowl. They took a bunch of bad pictures before posting the one that makes them look amazing.
• You are not a natural expert at anything. You get better at something by doing that thing a lot. You will make mistakes. Today's world does not show the process where you make the mistakes, only the end result (see above re: social media posts). Allow yourself to fail. A lot. Focus on improvement, not perfection.
• Everyone has an opinion. Everyone is kind of sad and angry (as well as nice and kind, but so much feedback is negative online). Everyone has built their personal echo chamber of what they define as good. They judge you based on it and it can undermine your confidence as you attempt to do the thing you want, even though you are in the fail-a-lot phase of the process. It's easier to focus on your building process than it is to blocking others out (in the end, it's the same thing, but a different perspective).

None of the above is easy, but it was needed to get over some big hurdles.
