Yes, but incompletely. I'll track things precisely until a habit is established, at which point I stop tracking everything and check-in every once in a while to make sure I'm still on track. Some things I keep track of consistently, such as my budget, weight lifting numbers, bodyweight, etc.

The process is different for different things. I usually start with a Google Drive spreadsheet, and then experiment with other more specific apps if they're better than spreadsheets (they rarely are). If you have any more specific questions, I'd be glad to answer them.
