Am I on the right track to becoming a professional cellist?

Pros

• I’m currently in the top ten academically out of about 1,000 students in my grade, so getting into a music school with strong academic requirements shouldn’t be a major obstacle.
• I practice 5–8 hours a day, consistently and seriously.
• I’ve already received a few full-ride scholarships to any university I want, which helps a lot given my financial situation.
• I’ve completely mastered Rachmaninoff’s Cello Sonata (Movement III), Yo-Yo Ma’s “Love Theme.”
• I can perform Yo-Yo Ma’s “Going Home,” Elgar’s Cello Concerto (1st movement), Fauré’s Élégie, Britten’s Cello Suite No. 1 (Canto Primo), Bach’s Cello Suite No. 1, and Saint-Saëns’ The Swan.
• Pieces I’m currently learning (which I aim to fully master by the time I graduate):
  • Britten – Cello Suite No. 1
  • Bach – Cello Suite No. 2 (Prelude and Sarabande)
  • Barber – Cello Concerto (2nd movement)
• I also will be regularly working on:
  • GDYO orchestra repertoire
  • TMEA All-State etudes
  • SFA Strings Camp repertoire (only during the summer)
• I get to attend Stephen F. Austin Strings Camp for free, which gives me access to good teachers and players.
• I’m likely going to make the Philharmonic level of GDYO, which would give me stronger ensemble experience.
• I’m willing to move anywhere in the U.S., or even internationally, if it gives me better opportunities.
• My long-term goal is to earn a DMA/Doctorate in Cello Performance (or an equivalent advanced degree).
• I will likely earn a Division 1 rating at TMEA State Solo & Ensemble.

Cons

• I started cello at 12, and I’m almost 16 now, which is later than many professional musicians.
• I live in a very poor area, and my family is also poor, so I can’t afford many competitions, festivals, or travel opportunities.
• My high school orchestra program is very weak, so I don’t get much challenge there.
• I didn’t start practicing seriously outside of school until my sophomore year, so my intense training is still relatively recent.
• I have some natural disadvantages:
  • Slow learner
  • Several hand complications
  • Scoliosis
• I also struggle with severe performance anxiety, including panic attacks during performances.
• As recently as last year, I couldn’t successfully perform even a Grade 3 solo (La Cinquantaine).

Even though I started late and had a rough start, my progress in the last year has been extremely fast. I went from struggling with intermediate pieces to working on major repertoire and practicing many hours every day.

So I’m trying to figure out:

Is this the trajectory someone on the path to becoming a professional cellist might realistically have, or am I still too far behind?
