Calling all cellists!?

I'm from Alaska, and I've been playing for almost 4 years(I'm only 15). Cello plays a huge role in my life. I love it and it's kind of taken over my life. The hardest thing for me to learn was the prelude to the Bach cello suite #1. That took forever and I'm still learning it! And yes, I know a little about how a cello works and what the luthier goes through is like . I researched it a little bit for a report in 6th grade. And if you have any tips for learning the prelude, please let me know!
