Everything has room for improvement

Above is a guide teaching someone how to draw a realistic looking water droplet. Look at how well it is done. It shows the whole picture, highlighting the key components. Then it shows the stages it should go through in order, and lays out tips to help the user. In the bottom right corner it shows an advanced version of the principle applied to a heart-shaped water droplet.

If a guide this good can be made for water droplets, certainly we can create operating procedures, lectures, instructions, recipes that step things up significantly. There is always room for improvement.
