A photography reference is most helpful when it answers a question you can test. Start with a specific problem, such as motion blur, colour casts or a distracting background, rather than collecting general tips.
Turn information into an experiment
Write down the variable you will change and what you expect to see. Make a short comparison series, keeping the subject and other settings steady. Compare the results at the size in which you expect to show the photographs.
Keep both successful and unsuccessful examples with brief notes. The record makes it easier to recognize the same problem later and to choose a technique for a reason.
