Sure! Helped plenty for me.
I practised in front of a mirror too, bit like, 1-5 minutes daily.
At one time, I just looked at the mirror and thought I should smile to express the happiness I felt at that moment. I'm usually about happy/content/something along these lines. That's when I got the idea to practise.
I don't so this anymore though.
I about reached the maximum possible at the moment and my facial muscles hurt too much from screwing up my face anyway.
Smiles and laughs are good and refreshing, but everything else is taking a toll on me actually.
If I frown twice my face hurts, literally haha
