Practice and Information
There are 2 period of time for me, practice time and information time.
How many songs you listen to, I can not become a pianist, how many times we watch a Marathon on TV, we can not become a Marathon runner. At that time, all I need is to practice, not information. Things I can get from information is limited.
After lots of practicing, sometimes I confront a big wall of difficulties, which so called slump, steep curve of growth etc, I need some tips and information to break through these barrier at that time. In that situation, information will be really useful.
