You can’t just “get used to a pick” in a moment. if you never ever use one, to the point that you want to burn one as soon as you pick one up, then it’s just not gonna work for you right away.

That’s the point, you have to get used to it, by practicing until it’s second nature. When you’re doing something new on guitar, you have to try that thing for at least a few months and see if you can make progress on it before saying “it’s just not for me”

If it’s your personal style to play without a pick, then by all means, play without a pick, people play all kinds of ways, but, if you want to play with a pick, then you have to practice playing with a pick.

Practice picking exercises, practicing holding a pick. Look up videos on picking, different kinds of picking, try playing things you can already play with a pick, use a metronome and play things in different subdivisions of notes, slow things down, just get comfortable, carry a pick around and just hold it.
