I was brought up with a dose of “if that was such a great idea, someone would have done it…” and so we are taught to bury our heads, work hard along the paths well trodden.
The strange thing is that we think any deviations are supposed shortcuts. That people who might have gone down a less trodden path might have sacrificed something important – maybe their morals, or they have had to work harder, or they had to – God forbid – take risks.
Why can’t the someone be you? If it’s an idea dealing with an issue you care about, why don’t be the one doing it. And then pivot when challenges come, take the feedback you deserve and work on it. Until you get it to work. And it works because you did the work. Not because you left it to that someone else.
