learning kotlin

Hello, I’m trying to learn kotlin and I’ve been following a beginner book. I’m getting towards the end and realised I’ve not learned how to do anything by myself as I’m just following the book it feels almost like a waste of time. I understand the theory its teaching.

Is there anything else someone can recommend on how to learn kotlin for beginners? with exercises and problems to solve not just examples

P.s I don’t know Java or any other language

Thanks
