I felt like this before. Now it feels more a matter of time. I got significantly better by observing talented colleagues and picking up their strategies, some like: Have a hypothesis and try to prove otherwise. Start cordoning off parts of the codebase where the problem ISN'T. Leave printf breadcrumbs to trace execution. I find my less capable colleagues make the mistake of false assumptions, like some subroutine is executing or what state an object is in without proving it to themselves. That keeps your investigation from proceeding without luck on the larger problems.
