Wanna Be Agile, But It Makes Me Feel Sore

Just like the word "athlete", the word "agile" grabs your attention; it sounds great. But going from desire to reality always tests your commitment. I feel good after a vigorous workout but then the next day (since I don't work out as regularly as I should) I feel sore. And then I don't want to go back to the gym. Agility makes you sore at first too. But it gets a lot better if you resolve to stick with it; after a while you don't get sore at all--quite the opposite.
It's no different in business.
