How many microgym owners are still stealing time from the business and their clients to perfect their own fitness pursuit?

Too many.

Too many of us are still spending HOURS per day to increase our own fitness, purse some pipedream of being a competitive athlete, etc.

Guess what?  You own a business now.  That is your new sport and passion.  Continue to enjoy fitness and stay fitness, it's good for the mind and body...but it's time you really analyze if you're acting selfishly and outside your lane now that you own a business.
