It makes sense that if you want to play like a pro you need to be practicing like one but how exactly do they practice? This complexed question can't be answer easily but I can offer some insights. Pro players are first and foremost consistent. They are unlikely to miss a day of practice. They might miss many things but guitar practice won't be one of them. So begin by being consistent with your practice. Pros also focus heavily on mastering techniques. They don't jump from one thing to another. When they start something new they will either decide quickly to abandon it or will commit to seeing it through. Pro guitar players don't want to waste time so they make decisions early. My third tip is to study with a pro. The best way I know to become a pro player is to get a pro to coach you.
