I went through it page by page, each day I started I'd go back maybe 5-10 pages. I do contrawise 2 handed scales as a warm up. I've been approaching it as work (ie concentrate hard, do deliberate practice not messing around) and have seen really fast improvement. I practice maybe 30 mins 5 days a week.

I'll also just have fun - I just try and play the songs I really like (Greensleeves, Scarborough fair, House of the rising sun, Canon in D etc) until they're really good. I can (barely) play Canon in D after maybe a month (though I played Violin for 5 years and piano for 2 as a kid)

If I don't know a song, I'll google it before tackling it as I find that makes it way easier, eg here's Canon in D https://www.youtube.com/watch?v=jFRYPg5dwss

You can also download sheet music, eg Aphex Twin, and easy version of Europe's the final countdown etc which is pretty fun to play as a synth.

Good luck!
