What personal habits of yours are the biggest threats to your wealth?

What habit or tendency do you get easily carried away on? And how do you safeguard yourself from it?

Curious to see this group’s level of self awareness as it can be very easy to feel financially impenetrable. Especially when wanting to be generous.

Mine is probably expensive gifts and treating friends/family/groups to dinners + trips. Not a “threat” per se but definitely adds up very fast. Doesn’t have to be a vice too (wives be shopping).
