Anyone will tell you the best way to learn is through experience, I prefer to learn from the mistakes of others however. It tends to hurt less. So yeah, what have you learned recently through trial and error or simply error. I'll start it off. - Don't dance in the shower, its slippery, you could fall, grab the curtain as you fall, pull it off the rod, and flood your bathroom with water from the shower head. As tempting as it may be, stick to just singing.
