Why should we play it safe?
Why should we feel bad to compare ourselves and our results to others - why should we even compare anything to others?
Who says we are competitors? That only happens if you have a carbon-copy, fungible commodity.
But, even if you and I wrote books on the same topic, they are not fungible - they speak differently - they have a different tune - resonance. it is quite possible that my book's tune my appeal or affect another, while yours might make an impression on someone else.
Why should we self-censor and beat ourselves down into a cog in the wheel?
For what?
When I'm afraid and think I should conform, I think of my kids - do I want them to grow up and conform - just be someone in the faceless crowd? Or do i want them to shine and contribute to humanity - do the thing for which they are suited?
