learning piano

so i bought a keyboard back in april. i've never played before, but luckily the first 2 octaves have the note written above the key ;). so i just kinda put my nose to the ground, and slowly started teaching myself to play midnight sonata. but it's been months and i've lost a bit of what i've learned. i definitely picked it up quicker than guitar, which i didn't expect, but i really want to get better. should i just find a teacher? how did you guys learn to play? i've always gone the self-taught route with almost everything i've done, but maybe it's time i swallow my pride and get a teacher. just curious for some opinions and maybe learning exercises.

oh, i saw pianomarvel.com, think i'll do the free trial and see what that's all about.

Pride?
Get a teacher.

It's possible to get fairly good at the piano without lessons, but the things you learn from one-on-one lessons with a good teacher (like proper finger articulation) will enable you to go much, much further.

biggest regret of my life is not starting to play piano with a good teacher from the age of like 5.
so so useful later on.
