Expert advice is a starting point, not a finish line. Try it, then see if it fits your situation.

Advice comes out of somebody else’s situation, which included their body, their schedule, their equipment and their luck. That makes even good advice a guess about you rather than a conclusion. Following it exactly and getting nowhere is not proof you followed it badly; it may simply not fit. The only real test is whether it works in your life, and you are the only person who can run that test.

Take one piece of advice you have been told is correct and try it properly for two weeks. Note what actually happens, then change one part of it rather than dropping the whole idea.
