Hey. I'm Pierre and a total beginner here. I really enjoy the beginners lessons on this site and have been at it for about 3 weeks and can already see some progress... my question is how to pace and when to move on to the next lesson.

Should I wait that I totally master one before moving on to the next ?

What I have done so far is practice a lesson until I am partially accustomed to it, then move on to the next, but keep re-practicing the old ones daily... the problem is as I go through lessons is that the daily practice adds up and I still can't say I master the earlier ones... Am I on the right track ? or any other tips I should know about ?
