Don’t mistake a cause of a problem with the real problem. “I can’t get enough sleep” is not a problem; it is a potential cause (or perhaps the result) of a problem. To clarify your thinking, try to identify the bad outcome first; e.g., “I am performing poorly in my job.” Not sleeping enough may be the cause of that problem, or the cause may be something else—but in order to determine that, you need to know exactly what the problem is.
I don't have time - cause of a problem
Being little flexible, procrastinating - problem
