This reads like someone who has english as their second language. I say this because an American would translate this more poetically, instead this phrase is coarse with barely a figurative expression.

"Those who focus on the footprints in their wake, lose the opportunity to take flight". That would be a better version of this quote.

Everyone's entitled to their own opinion. You're arguing for everyone to share the same opinion. That, sir, is an echo chamber.

The point of the quote is to do something even with risks, as opposed to doing nothing with no risks. What's the point of life if not to have your point of view being at risk to critique? Under your own frustration you missed the point of the quote as well.

It's ok.
