It all starts with a big heart and a big dream. Getting to the top is the catch.
It can be complicated but it is worth a try and don't give up no matter how hard the piece is.
You have to learn the basics of getting the notes right and working hard on the rhythm. Keeping a steady beat. Come concert night you have done your best and worked very hard on getting everything together. It is your time to shine and after it is over you feel accomplished and ready to start again with new songs, difficult rhythms, fingerings, and so on and so forth. In the end it is worth it
