One thing I have come to realize, is that worrying about bubbles will keep you poor.

If everyone is in the bubble and it pops, everyone is in the same boat, so you’re not really going to be poorer than your peers by comparison.

If it’s not a bubble and you are wrong, you will fall way behind everyone else and just watch people get richer and richer doing the exact same thing you should have done.

Also, just because something is a bubble doesn’t mean it has to end in a devastating pop. Sometimes bubbles expand and then just get diffused. The exponential rise stops and prices plateau, but it just becomes a new normal and things stagnate for a while before resuming normal upward growth.

Ask Warren Buffet how concerned he was of "missing" on bubbles... He got richer than pretty much everybody else by just avoiding bubbles and then buying assets at fire sale prices when they inevitably popped.
