I agree with everything you say, except the following:-

"Let go of your fears . . .when one arises, ignore it. "

Recently, @cryptogee convincingly explained how, when we try to ignore a worry, it actually festers and grows.

Instead, the correct response is to give your fear a name (he uses the name "Nigel" lol, but you can use whatever annoying name you want), and then once named, acknowledge that fear, address it by name, and tell it to go eff itself.

I'm only just starting this approach, and I can say, anecdotally, I am finding this approach a LOT more effective than trying to simply dismiss worries. :)
