What's the idiomatic verb that goes together with the fulfilling of a promise?
Some example I thought of - are:
Please, if you promise something, then _____ it.
He always _____ his promises.
I don't like to promise promises if I don't know for sure that I'll____ them.
It's very good to promise promises but it's even better to____ them.
The words that I can think of are: fulfill, do, make it true.
