define wrong ambitions.

I get from the text that you can have peace of mind and progress towards your goal. That peace of mind allows you to progress easily, less troubled. It doesn't say your ambitions are invariable once you choose them.

The fact you realize your original ambition is not what you want anymore you still got all the learnings from the path.

You missed my point. Wrong ambitions that I'm talking about are the ones that make you take actions that have consequences, you chase an ambition that makes you lose other things and you may only realize that once those things are lost forever.
