Help with quant prep

Hey could somebody please help me with how exactly I should go ahead with my prep for quant
Because right now it is very unorganized and scattered.

I am keeping a target of just 20 to 30qns a day but I am not able to meet even that because I panic when I take too long to solve a qn and I then jump onto something else entirely.

Ideally how long should I try solving a question on my own before checking the solution?

Because right now there are instances where I sit with ONE question for like 30 minutes or so because in my mind I have convinced myself that looking at the solution means admitting defeat

Which feels stupid typing out but that's the psychological process I am going through these days and it's not getting me anywhere.

There is no positive change.
