From the basis of his disappointment shown when failing in Celestia’s school, he must have made serious effort whatever dire circumstances and experiences he had to go through just to achieve his goal.

Nevertheless, when things didn’t go exactly as he hoped for or wanted it to be, he still didn’t gave up, even if at times his condemning feelings made him feel reasonable to do so otherwise. In the end, at least he became something.

This is a good lesson for us. =)
