Mastery of a skill is always a plus. especially ones that involve working with your hands, its really great to see your works in front of you, self expression takes many forms, being unique, i guess that was the beginning of arts.
well, if you practice a skill and you watch your hands over the time, you will see that you hands take different shape depending on the skill you have developed and for me at least, a craftsman equates to an intellectual because each has something unique.. sometimes i wonder why labor men are so much underpaid, though they have remarkable skills..
I have a friend who is a painter, and when i used to see him sketching, i used to enjoy watching how he draws the lines, moves his wrist, holds the brush, another one was a pizza boy who used to make the dough, i enjoyed his sense in cutting it and shaping it to exact weight portions based on experience, its like your hands can work together with your memory and senses to refine a calibrated mode with practice. its amazing.
The joy you get when working with your hands is worth it, playing an instrument or playing with clay, play dough, chef like skills such as chopping something so fast, have a sense for textures,, painting the walls, cross stitching, making cards, planting with mud all over your hands,, carpentry or even playing with yoyos..
These are different and stimulating kinds of exercise and its more joyful when you have company.
