To continue with the singing theme from yesterday: Do you ever struggle to hit those high notes when you're singing? Do you ever get choked-up (literally) with emotion or nerves or just plain tension? Next time, try opening your mouth a little more. See what happens. ;)
In our bigger, better, faster, more society there's an awful lot of jaw clenching going on. You might not even know you do it, but chances are you do. And chances are you can afford to let that tension go, open that mouth just a little further and let that voice out!
