[Help Thread] How can I get sub x on 3x3?

[turtwig]

Is there anything that I could watch or read. I won't lie when learning f2l I didn't really do the proper research. I just googled. How to solve a Rubik's cube faster. And watched the first video. So I feel like I've missed a lot. And there is somethings I don't really understand.

Try this video, it's the one I watched and it really helped me learn F2L.
