Here is a common concern I receive from students and thought I would address it to everyone here.

Dear Lisa,

I never smile when I practice. My sister says I am too tense. I am having difficulty learning,
can you help me?……

Relax. You are concentrating too hard and not enjoying the
learning process. Learn to be happy with every little step, no matter how little.
Next time you sit down to play the piano, start with a smile and tell yourself that even though I might not be playing the way I want to yet, I am still playing and enjoying the journey to get there.
Think of where you were before you starting learning piano, and tell yourself that everytime you play, you are getting closer to your goals. Here are some steps to manage your smile:
If you are tense because of difficulty, then you need to back up in the lessons and
go back to where it is easy, and progress a little slower.

Good luck!

Lisa
