The Beatles – Let It Be (piano cover) play by ear no sheets

I play piano, and learn songs and play them ( i play entirely by ear) like so far i’ve learned "what i’ve done" "the phantom ofh the opera’ various beatles songs…etc. so what should i learn to play next?

I just my first guitar for Christmas and I want to teach myself by ear. I’ve played piano for two years. My friend taught the chords A, Amin, C, D, Dmin, E, Emin, Gadd7.
With this I taught myself Last Kiss by Pearl Jam. I’m a big fan of Bob Dylan, Led Zeppelin, The Beatles, Love, The Kinks, U2, and hundreds of others. What songs would I be able to figure out and play by ear?

I can play, but only by ear. I can play a few songs such as: River Flows In You – by Yiruma, Let it Be – by The Beatles, Imagine – John Lennon. But as I said, I learned them all by ear, and watching videos.

What can I do to learn sight reading? And I don’t want to take lessons.
