Here is my minimalistic routine:

No shower.
Open hot tap (you could pour hot water out of a kettle) and wet brush with hot water. Close tap.
Swirl brush on top of soap (that sits tight in its container) till bubbles appear.
Immediately start building lather on the face.
Strop the razor with lather still on face.
[mark]Hold bruch upside down and push a pocket in it with index finger. Fill pocket with a bit of hot water from tap (or from kettle).Swirl three circles over soap.
Rework the lather on the face.
Shave first pass.
Repeat from [mark] and perform second pass.
Cold rinse.
Alum block.
Clean brush and dry razor with small piece of toilet paper.
Aftershave? What's that??? Never heard of.
Rinse off dried Alum with water.
Done.

Takes 6 or 7 minutes. Uses a minimal amount of water. No more soap than strictly needed. 1 alum block every 2 years. 1 roll of toilet paper a year.

I really do it that way. But not always. I have elaborate schemes too...

Best regards,
Bart.
