Oh yeah, in the beginning, you'll probably screw up, but it'll still be edible, and then you learn where yo uscrewed up. Start simple, build your way up, it's the same as learning anything, you start at the beignning

Any skill takes time patience and dedication to learn, be it cooking (or coding, cause I run into it a lot in coding, people expect to be epxert in less than a year)

Mark Bittman's How To Cook Everything series is pretty good. The photos don't correspond exactly with every step, but do a good job of showing you what things should look like at important stages.
