I only know three openings

Kings indian attack as white and 1. C6 as black for whatever. I have been playing for quite some time and I'm just bored to learn another opening. It will takes hundreds of matches to fully learn the opening and middle game techniques and I never have the motivation or the time to do it. Half my losses are due to my ineptitude in Slav. I'm wondering if there are other procrastinators here.

Just stick to it so as to accumulate experience.

i now a lot of openings but it just makes me brain pop when i try to remember theory for some opening that i havent played for some time. Better stick to the stuff you know.

Or maybe don't bother with learning theory but try to play decent chess.
If you are weak you don't lose because of the opening. If you are strong you don't win because of the opening (OK, if you have a FIDE rating > 2600 than that does not apply).

I know the general theory most openings, but my procrastination prevent me from switching openings again. (There are other factors, including failing eyesight and lack of motivation.) Strangely enough, I often play the KIA, but never bothered to learn the KID well enough to play in a serious game.

To the OP i hope this makes you feel better

...

Hmm. The OP's account was closed.

Try to stick to simple, easy to remember openings, like the Spassky variation of the Ruy Lopez (1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. O-O Be7 6. Re1 b5 7. Bb3 O-O 8. c3 d5 9. exd5 Nxd5 10. Nxe5 Nxe5 11. Rxe5 c6 12. d4 Bd6 13. Re1 Qh4 14. g3 Qh3 15. Be3 Bg4 16. Qd3 Rae8 17. Nd2 Re6 18. a4 Qh5)
