Stop worrying about P/E.

If you had only invested in companies with sane P/E in the 2010s you would have probably missed some of the biggest runs for companies that today are some of the most valued in the world.

Worrying about P/E is more for really big institutional sized investors who are very conservative because the loss of principal is far more difficult to recover for even small % of loss.

You are an individual investor who can probably recover losses with a year or two of salary.
