If you're browsing on a desktop, configure your account to always use the old reddit experience. If you lurk without an account, use old.reddit.com. If you can, install RES, it's a game-changer.
If you're browsing on mobile, don't use the official reddit app. It's garbage. Use one of the many 3rd party apps. Personally, I use Bacon Reader.
Don't bother ever browsing /r/all. Tailor your subscriptions to the subs you actually care about.
Try to find more niche subreddits. Subs like /r/AskReddit are just massive karma farms.
