Do some soul searching to find out if you really want to be a drummer. If your parents need to push (or sometimes shove you into practicing) then there is something wrong. You probably shouldn't pursue drums. When I just starting out, I didn't have a drum set. During the school year, I would stay after school to practice and during the summer, I would walk to school (carrying an arm load of records to learn from) to practice on the school drum set. There needs to be a passion from within.
Try at all times to be positive and professional. A great attitude will get you farther than you may think.
Try to be one.
Some things take time, be patient. Some of the lessons will be very challenging and will not be mastered in a single day, take your time.
The general rule here is, make sure everything works, sounds good and looks decent. It is all part of being professional.
Listen to what is being played around you and how you are locking with the other musicians. Play in context and make the other musicians sound good and you will sound good as well.
CONFIDENCE verses EGO:
Knowing the music and your parts will give you confidence in your ability to handle the demands of your situation. Let your music speak for itself.
PRACTICE is EVERYTHING:
Like most of life, you get out what you put in. Practice is the investment that will return the skill, competence, and confidence of playing the drums well and being a good drummer. See practice guidelines.
