You do advise clients, don't you, that past performance is no guarantee of future results?

I try to remain neutral on this issue.  I don't help clients pay their taxes, I just prepare their returns.  But if other people want to add that service, I just hope they charge for it, and follow the Musk-RFKJr rules.  Just because self-driving works most of the time, always keep your hands on the wheel and your eyes on the road.  Just because vaccines prevent millions of deaths, always make sure your own estate plan is up to date.
