Can you add more detail here? What is your prediction? That they will (1) change their mind and not be at peace, because this feeling doesn't last or (2) they will not accomplish much because ambition is not compatible with being satisfied?

(this is my wild guess based on the tone of your post, just trying to understand it)

My 5 cents is that sometimes you can reach your ambitions and it might be hard for you to get new ambitions, no matter how you feel about yourself.

It can also happen that you end up with wrong ambitions and only find out once you reach those ambitions.

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.
