Very good tips from Mariko!
I’m also a beginner (been playing for 9 months).
I recommend getting a good practice plan in place. I follow Michael’s practice plan and it works very well. Lets say if you do 30 minute playing session, the first 10 minutes should be split between exercises and scales. The next 10 minutes should be your studies/etudes. The final 10 minutes should be any songs you want to learn.
