Progress

To improve at anything you need to try. To work at a level a little above what you are capable of. Not too much that its too hard and you give up, not too little that you get bored.

The key is to train above your current ability. If you stay within your wheel house you'll never improve. Take driving, you most likely do it every day, but are you becoming a better driver, doubtful, possibly even worse, as you get bored loose focus, play with your phone while driving. But there is better, look at formula one drivers, rally car. Its not just the time, its the working at and above your limit.
