Practice Time vs Wasting Time

Eli Prinsen talks about the countless hours that can turn into days, weeks, months and even years of simply watching free training content found on youtube, and not spending some of that time actually practicing.

How much of that time could you actually be practicing? what if you devoted an equal amount of practice time to what you spend watching videos? 

Also, how many different techniques, tips or exercises from the multitude available from different sources have you tried? Did they "not work" the first (and possibly only time) you tried them, and then moved on to the next video?

Are you even attempting to try and stick with any method and give your voice a chance to improve?
