Over lubrication is the primary cause of premature bearing failure.
Check out lube recommendations on the bearing or grease manufacturers
web site. Depending on the capacity of your grease gun usually a
couple of shots periodically will suffice.

Is that true? What damage does it do to the bearings? The worst I've
seen is for the excess grease to squirt out and make a mess.

Too much greease in a high speed bearing can very easily cause it to
overheat.
Small 1800 rpm motors will have no problems with overgreasing other
than the mess.
