Not only we ought to manage small projects but also we ought to manage one small project at a time because juggling multiple projects can easily overwhelm us.
It’s better to master one skill first than trying to learn multiple skills simultaneously. It’s easier for our brains to process learning one skill at one time.
When the skill is mastered, then we can learn to master another skill. Some of us have the tendency to read and learn and read and learn again without ever applying it to something.
Instead, read the material, learn the material and then apply the material; that’s what makes things worthwhile mastering.
