DeGoogle Yourself

Get two or three emails. I use Proton for bullshit. That means job applications, news subscriptions, normal shit. Then I use Tuta for serious stuff like doctor's appointments. Then for all your fun personal shit, use another one that is more anonymous if necessary (I rarely use it.) The point is, it is better to have at least two.

Do not get rid of gmail for a while. I have had my new emails for a year and like the other day I needed it to use Steam. I only get into gmail on my work computer at home or my Windows desktop which I assume is being watched/tracked (typically use Linux) when I absolutely need it (usually a password for some stuff I forgot about.) I will delete it eventually. I delete stuff off it sometimes and so should you, like the stuff on Google Drive and start using a different calendar.

Change bank account and brokerage emails. Change Steam email if you use it. Start using the others and just don't login to gmail unless you have to, and only from a shitty device that you don't care if it is being tracked. I might put Linux on that desktop soon and keep the Windows partition while I finish getting off Google just so their shitty trackers are not on all the devices I care about.

Good luck! You got this! It sounds harder than it is and you'll feel so much better to just take that first step of getting a new email.

Edit: Also, I made another new gmail account just because proton forces you to import all the shitty spam from google. Or at least I couldnt figure out how to fix it.
