When you're practising a skill, the basics eventually start to feel rote. You've used the skills from your first lesson over and over, so it feels boring practising them. The fact that you use them constantly, however, is why you need to keep practising them.
As business blog Entrepreneur explains, every skill, trade and profession has a set of fundamentals that are key to overall success. While you can build on top of those skills, you'll keep coming back to the basics over and over. For this reason, they're among the most important skills you can practice. Entrepreneur uses the example of former Green Bay Packers coach Vince Lombardi:
Lombardi's methodical coverage of the fundamentals continued throughout training camp. Each player reviewed how to block and tackle. They opened up the playbook and started from page one. At some point, Max McGee, the Packers' Pro Bowl wide receiver, joked, "Uh, Coach, could you slow down a little? You're going too fast for us." Lombardi reportedly cracked a smile, but continued his obsession with the basics all the same. His team would become the best in the league at the tasks everyone else took for granted.
Think back to the things that you learned in your first lessons, or first days on a job. These are the things that were deemed important enough to start with. A better understanding of these concepts will help you improve. Adding new skills is fine too. But these are the ones you'll need every day.
