I find that to be an interesting statement. Do you mean that you were injuring yourself when trying to stretch for the splits? Is "happier" due in part to being now able to meet your goals?
No injuries.
I spend the time I would have spent doing intensive stretching working on mobility, GPP, and strength training. As a result, I move much better and more effectively. Foam rolling and dynamic mobility work has paid dividends, stretching to do the splits really hasn't.
Happier wasn't a word I used but sure, I'm happier because I'm healthier and more athletic.
