hello. i've been interested to play the piano since small but never got the chance/money to do so.

I have a keyboard at home (with lesser keys), and i cant really play it, lol. I was thinking to get piano lessons but it's out of my budget since i'm still a student.

Do you guys think it's possible to learn how to play piano without attending the class? I'd love to learn from someone but nobody would teach for free. (practical and theory lessons) I tried on youtube but it's very hard for me to follow. :/

I'm 20 this year btw.
