This became my favored method about 6 months ago.

After doing a complete scrub of my entire face from the soap
puck, I start adding HOT water a bit at a time by dipping the tips
of the brush. By doing so, I slowly build the lather, and it stays
hot the entire time, instead of cooling off in the first 10-15 seconds.
Strop, and then do 'da dip again before commencing the shave.
Pure comfort!

The thing I like about it is that I spend about 2-3 minutes in lathering
up, and have warm lather the whole time. Then, after the 1st pass,
I just dip the tips of the brush slightly, and it's warm all over again.
