David,  here's another way to convince yourself you have the time:
For the next week, count how many times you repeat the same "hand-test"
of some code on a subsequent version.  Think of how much time that can
add up to if you no longer do that; you had-tesing time is subtracting
from the time you have to do unit tests.
