Is it ok for me as a 16 year old turning 17 in 3months not to know what I want to do with my life?

I’m stuck with it seems no way out. I have an interview tomorrow with a bricklaying course, but I’m not sure if that’s what I want to do. I don’t know if it’s what interest me, I know what does interest me, but it’s such a difficult career path to enter into. Any ideas on how to handle this? Thanks.
