I‘m not an abrasives expert, but I know that coarse sandpaper (“grit range” 60-80) is good for rapidly removing large amounts of material, while finer grits (320+) are used for polishing and finishing work. Whether attempting to turn a block of wood into a race car, or tackle a major life project, I know I’m going to need grit. When I face adversity or undertake something that is emotionally, psychologically, or spiritually taxing; I have come to find I also need grit to smooth out my adjustment to whatever scenario comes my way.
