Avoiding Dogma Part Gajillion

Very few things are universally good or universally bad.

I spend a fair bit of time trying to learn about diet and exercise for a long list of reasons related to financial/retirement planning (spending more or less on health costs would seem to be relevant), trying to help my colleagues in the fire department be healthier (better fitness improves safety) and for selfish reasons (I want as long of a healthspan as possible).

I saw the following Tweet from Eric Topol and you can see my comment.

Diet and exercise is one of several topics I follow on Twitter and so I see links to studies all day long that conclude Keto is clear and away the best path and conversely links to plenty of other studies that conclude Vegan is clear and away the best path. Both could be equally effective, one better than the other or both could turn out to be totally wrong. In doing research I have drawn conclusions that I feel are right for me. The conclusions I have drawn will either turn out to be right or wrong down the road but I believe my healthspan for being 53 is pretty good so hopefully that trend continues.

So it is with investing. There are countless strategies that totally contradict each other but can both work. Day trade versus longer hold. Active versus passive. Sell your winners versus sell your losers. Be value investor versus be a growth investor. Momentum versus contrarian. Technical analysis versus fundamental analysis. Long only versus short only versus long/short.

This list could go on. There are successful practitioners of all of those disciplines and failures with all those disciplines. To proclaim one wrong and one right is silly. I don't believe in short term trading for example but plenty of market participants do it successfully. Wrong for me, sure, wrong for everyone is, to quote my Tweet, ridiculous.

Paraphrasing Joe Moglia, no one will care more about your <fill in whatever you want here> than you so put the time in to learn and draw the best conclusion for yourself on all fronts, not just investing.
