Keeping a builders log

Ok, I've been building my plane for the last 2 years. A wood and fabric
plans built.
I purchased the raw material and milled everything myself. Up until
recently I've
kept a buiders log on everything I have made, built, and glued.
Question. Do I need to log every minute? There are days after days of
cutting very small
pieces and glueing 1,2, and 3 peices at a time, let stand overnight,
and glue 2 pieces again.
There are times that its only 2 minutes. I'm not complaining, I'm
really enjoying the woodworking. But, do I need to log every minute or
is there a better way to log the week?
