Deliberate practice is definitely a good thing. In order to know what we need to work on, we should be doing certain things including counting with the metronome, checking with the score to find wrong notes. Listen to online recordings of the pieces you're working on.
When something is technical, I'd try different fingerings to "discover" what the things that work best. The last thing is a quick recording with a phone and listen to the playback. A good 1 minute recording we'd be able to pick out the spots that need work than repeating the same sections aimlessly.
Many of us play music as a hobby. 10,000 doesn't mean much unless we're aiming to become a professional. Practicing just 1 hour a day for a year would take 27 years to reach the magic number. Your progress is relative to the time you put in. If you put in just 10 min a day, the progress won't be as significant as someone who puts in 5 hours a day.
My last practice session was at a public piano in a shopping mall. Had copies of scores on my phone. I wasn't playing through entire pieces than just a few bars I had trouble with. Practicing in public lose the fear of people after a while. Most would walk by without paying much attention.
I came across a short video from a piano teacher who suggested the fastest way to make progress is to play in front of people regularly... can be a game changer. I know some people made comments before they have been taking music lessons for years but never played in front of anybody or feel the need to play for anybody except for a teacher or the examiner if they choose to take conservatory level music exams.
