The most effective way to get better at something is to engage in deliberate practice
When practicing something, work on something just outside your current abilities
Stay actively focused on the current task. Consider using focus techniques
such as Pomodoro.
Practice time is not sufficient. Deliberate practice time is required.
The 10,000 Hours rule applies to deliberate practice, not coasting
Do not multi-task. Multitasking is almost universally a bad idea and results in the belief that more work is getting done, when really less is getting done and your practice isn’t deliberate.
