My Mum got me this card, as she knows I am interested in RE. Thought y'all might like it.
That seems to encourage the puritan work ethic - i.e. you must work, even if you're FI.
In other words, it seems like your mom is sending a message that you aren't on the richest list, so you should keep working, and not ER. That's how I read it at least.
To me, getting on the richest list isn't a goal, so why would I check for my name there?
Different strokes. :)
