There is something magical about a guitar; A hollow, wooden instrument, with 6 strings strung on top. The strings must be tightened to a particular level and when the strings are played by someone placing fingers in a particular formation, music emerges from it. People that have played instruments have brought peace, change, exhilaration and joy to people throughout the ages.
Maybe a guitar isn't your thing. That's fine, maybe it's keyboard, woodwind instruments, or something else? Did you ever play an instrument when you were school? Remember how it felt to play?
Whether you play by yourself and sing along, or play with others in a band. Music is one of life's greatest gifts. You need to make some.
I encourage you to find that old instrument, and reacquaint yourself with it. The internet has alot of beginner tutorials and videos to help people learn to play just about any instrument. Many are on youtube, and can be viewed for free.
Music helps us release stress, strengthen our creative "muscles", and send out some joy that the world needs so much. Maybe you can find someone to help you recapture the musical skill you once had, and maybe you could find a group that you can play with. Practice takes time and effort, but sharing a musical gift can be worth it.
Just remember, the older you get, the less things you can participate in and call it playing. Learn to play, and share a gift you may have. If you don't have the gift, pass the instrument on to someone who will use it.
