8th grade promotion speech?

I'm Brianna… And I would like to welcome you all to the 8th grade graduation of the… Class of 2014. Before you is one of the largest classes with 141 students in the grade. Over the past 4 years, we have grown together as peers, and have grown together as a class.
Henry Ford once said, "Life is a series of experiences, each of which makes us bigger, even though it is hard to realize this. For the world was built to develop character, and we must learn that the setbacks and grieves which we endure help us in our marching onward." This graduation marks the end of our middle school years. Along the way, all of us have at least once been angry, sad, nervous, or excited about something. There has always been at least one struggle throughout your middle school years. It happens to everyone, and isn't a bad thing. These experiences just help us build character. They set you up for what life is going to throw at you later. These struggles will make memories that will remind you of what you have accomplished. They will last a lifetime.
It is now time for all of us to continue on with our lives and enter high school. As we sit here, and say goodbye to our last time here at…, we reflect on all of the joyous memories that happened the past four years of our lives, and anticipate the next four. Middle school was just one chapter in our lives, and it is time we begin to tackle the next.

If you wouldn't mind telling me if anything is weird.

Nothing is weird about your promotion speech I think that you did a wonderful job on it
