Hey Ruurtjan! Funny just replied to you on Twitter yesterday :)
I think any switch actually counts irregardless.
I feel you on the uncertainty thing. Quite honestly don't think you ever can escape this feeling. What helps is sort of going backwards from your imagined lifestyle that you want to live and how much you need.
Generally there is always a conflict of how much $ can I earn on the job and maximise my retirement account vs risking it with potential autonomy factor but less or no $.
Think the best we can do is just try to accept that feeling and do the best to achieve the financial needs necessary to keep going.
