When we become in tuned with a routine, we forget to live a life too, being spontaneous and doing something a little different. It can be scary at first because we aren't used to it and if 5 minutes is too much than do 1 minute. It's a start. Getting a little wild in the morning can do wonders not just physically but mentally too. You're not just moving around working muscles, you're also waking up the brain and getting blood flow to the body that generates energy, vibrancy and vigor. I'm not even asking you to go full boar, play with your own pace. Who said you had to stop playing as an adult huh? Life is more than just a routine, it's a chance to renew yourself and setting a different mindset that can lead to adventures, creating better moods and channeling your inner child.
Sure it is our responsibility to work, pay bills, do laundry and take care of a house but it is also our responsibility to live as well. When was the last time you saw a good movie? Wore something that was fun and exciting to wear? Read a book you couldn't put down? When was the last time you felt at ease and smiled from ear to ear for no apparent reason. Like you I struggle to live at times and need to remember that this life is our only one and do things that make us happy and feel amazingly awesome. Moving like a wild animal isn't some silly trend that is geared towards kids; it's a method that opens up a world we have forgotten and need to relive. It goes beyond exercise, it's an expression of freedom, the ability to challenge the norm and opening up our minds in a way that gives us reasons to smile and play.
You have a responsibility to live a life that has a lot to offer and it starts with a small build up of playing. Get wild after waking up and see what happens.
