There has been this thing called "practice" that good tennis players do which improves their tennis. Hard to believe I know but it really works.
I will surprise you...
There are theories about friendship, communication, education, teaching, even love. Thepries have major advantages over your experience, namely that they are not context-dependant and that they reflect reality objectively... your experience is unfortunately a biased sample.
You then have two options:
You guess that your experience luckily happen to fit reality in this case and you solve your problems through trials and errors;
Or you use the existing theories and you solve your problems systematically.
Guess what works best? In any case, you have good reasons to believe the theories will work every time: they‘re tested, unlike your personal convictions.
