How to master

Is it me or does anyone else find services, videos, books and websites that say… How To Master ________ in 10 Days annoying? Insert whatever you want into the blank; Facebook, Twitter, YouTube, Guitar, Drums, etc.

If that is all it took, 10 days, wouldn’t everyone be a master? I have been using sites and apps for years and can honestly say I have yet to master them, I feel very confident about my knowledge, but a master? It takes a lifetime to master something in my opinion. I am always learning something new, asking new questions, trying to gain more knowledge.
Do you think you can master playing the guitar, the bass, the drums in only 10 days? Of course not. How long have you been playing, have you mastered it?
I guess these things are designed to take advantage of most people’s desire to change or improve overnight. People that don’t want to put in the time. You know, just take a pill and fix the problem. You know, just sign a record deal and become rich and famous overnight. Few people have the patience to commit to becoming a master.
If you want to master something you need to commit your life to it. Nothing is as simple as 10 days.
