This is Dominic Miller, a seasoned professional guitarist and composer who has been working with Sting for the last 30 years, explaining how and what he practices. (There’s also a minute of “Shape of My Heart” done right)
The internet is full of “life hacks” and “the best thing since popcorn” types of clever advices. The reality is you’re going to get as good as the amount of time you put into it. You can be intelligent about how you use that time, but if you practice 1hr a day (like I do), you’re not going to be as good as another guy who practices 2hrs a day.
It all depends on how good you want to get.
