A closed mind is a small mind.
For each song lesson page we are adding a Random Guitar Tip. The one above was taking from the Lesson:
If Not For You by Bob Dylan
Most of the times we are solely interested in stuff that we like, and completely ignore styles of music that we don't particularly care for.
Keeping an open mind though can help us learn so much more than what we would if we just stuck with the usual.
Listen to as many different styles of music as you can, don't shut them out. Learn different strumming patterns.
That principle can be also applied to your life in general, be open to learn aspects of different cultures. :-)
