Think now or never. Why waste time; the clock ticks anyway. Put yourself 'all in' with your work. Hard work pays off. Ballet is tireless diligence but the rewards can be harvested daily in the studio or in performance. In some circumstances you may have to go a few rounds with your shoulder to the wheel before seeing the benefits but it's all worth it in the end. You may even find at times that hard work can actually trump skill. I was 13 years old and placed in classes with 8 year olds because I lacked basic technique. It took me 21 hours of ballet classes per week for an entire year to catch up to the talent that was my own age. The work didn't stop then either! So give a power punch to all the excuses that get in the way and crush it!
