Butch: "Hey, man, I'm getting a blistering high C and I want it NOW!" Bart: "Wow, my new picc just arrived! See ya later, man. It's Brandenburg or bust for me!"
Sorry, Butch and Bart, you'll have to be patient, and don't say "bust". You are welcome to go for it like a raging bull in the china shop, but you'll have to pay tomorrow for all the damages. Your practicing is not likely to yield the results you want just in one day, so go at it slowly, methodically, and carefully. No one learns to play like Maynard in one day.
Why don't you map out a strategy for your summer's building project? Be sure not to burn out. You must live to play another day. What you do today is preparation for the next day. Don't expect your finished product yet. No pummeling allowed. Balance blow with rest throughout your sessions. Don't play anything unintentionally.
This should be a welcome relief from undue self-imposed pressure. Simply plan on being able to pick it up and continue working tomorrow, still fresh as a daisy. For now, less brute and more brains.
