Both knitting and crochet are very difficult and frustrating at first. Harder, I think, than your first time picking up a guitar.
The initial hump is steep but fairly small. It took me about four or five tries before I could make stitches. Once I got over that initial challenge, it got a lot smoother. Since then, there have been continuous incremental challenges, but all fairly small.
I haven't gotten over the hump with crochet. I'm left-handed but knit right-handed because mirroring everything is very hard. The entire knitting world presumes right-handed knitting. However, I knit Continental style which uses both hands and engages the left hand a lot, so I don't find that it feels very "wrong".
However, with crochet, I don't think I could ever hold the hook with my right hand. But also mirroring everything while trying to learn is not easy.
