Always remember:

Playing a musical instrument is an incredible experience, but it requires some commitment.  Regular practice is ESSENTIAL to your success.

What is regular practice?
Regular practice means do a little bit each day.  It doesn't need to be a lot.  Fifteen minutes a day is plenty if the time is spent efficiently.

It is better to spread out your practice time.  In other words, 10 minutes a day for six days is better than 60 minutes all in one day.  The brain continues to learn during the time between practices.
