Giving credit away takes confidence. Insecure people hoard it.

Handing credit to someone else only seems expensive if you picture recognition as a fixed amount being divided up. In practice people notice who says the other name, and it tends to come back around. Hoarding is what worry looks like from outside: it signals you were not confident there would be more where that came from.

Say a specific name in front of someone who matters this week. Not general praise, but the actual thing that person did. Watch how differently they work with you afterward.
