My goal this week is to degoogle my life 90%
No maps, no gmail, nothing. I'll keep an account for YouTube and calendar only. For now.
The difficult part is updating other services and account to new emails.
Discussion
I move out in small steps... get your own domain (if you like long term), redirect the old email to the new one... update service as first needed first move and finally, close your gmail account.
That way you could de-clutter a lot.
