Giving up on privacy

I have been an advocate for privacy for a long time, but recently I don't even know why I am doing this anymore. I do most of my browsing through TOR, and that has made me give up a lot of conveniences. And that's what I miss. I miss not having to think about privacy. I also miss not feeling like I am being spied on. Now I am torn. I don't like companies like Google mining my data, but I also think I am being paranoid (the people in my life have shared this sentiment). I don't want to leave a permanent cache of my mind. But I also feel like doing so won't really affect me. Not to mention that I despise the predatory nature of advertisers, and I hate giving them even more info about me.

What do I do, Tildes? Have any of you felt this way? How do you balance running from Google while still staying sane?
