Fifty blocks done out of 150. That means there's 90 left.
One a day for the next ninety days means the blocks will be
done some time in March. Again, one block a day. Even if
you just pick the material out for the block, do that.
I get myself overwhelmed with the enormity of a project, and
I find I need to cut it down to doing pieces at a time. That
works for me.
