It sounds like you're in an awesome place!

The one change I'd suggest is this - rather than "I'm a failure," I'd suggest reframing it to "I fail."

It may seem like a minor, if not nit-picking change.

It's anything but.

If you really believe that you're "a failure," you risk losing motivation. Someone who *is* a failure can't expect success.

However, someone who has merely failed in the past can (and will) succeed if s/he keeps trying.
