Careful predicting the rest of your life based on 2 years of the best success you’ve ever experienced. Something similar happened to me 5 years ago and I’m operating on the assumption the crazy pay can disappear at any time. If you luck into a way to suddenly retire in 5 years, always assume there’s someone standing behind you willing to do it for less. Many money faucets eventually turn off.

The beauty of saving that much is I don't depend on it.

I have yet to save as much as I theoretically should be able to. Good luck, sincerely.

Edit: and you still have yet to demonstrate that your income will last for the next 5 years, let alone 15. Don’t count your chickens yet.
