I agree with the above, all of it.
OK, now to change slightly. The other advice I'd give, as I'm still going through the earlier stages too, is keep a Practise Log.
In the log set out what you plan to do over the week and use that as an agenda. Plan today what you'll do tomorrow, do it and log what you did and how well/badly you did. Put down also what speed the metronome was set at, that way you'll also see how you get faster. (Not that speed is the target, but it shows agility)
I've done this and it does give you focus and you do get progress faster.
