What is something you thought you knew your whole life and only just recently found out you were wrong the whole time?
Mine is that at my age (barely made it into Gen Z on the old end) I just found out today that a Bo Weevil is an insect (beetle) and not some kind of mole or similar rodent.
That's a direct translation; better English equivalents would be "give it a try" vs. "look forward to it".
They are pronounced similarly (tameshimi/tanoshimi) and either makes sense in context (usually heard at the end of an ad), so "Please look forward to/get excited about X" and "please give X a try" both would make sense.
