Very, very minor edits. Interesting speech!

Good morning ladies and gentlemen, 

Today I am going to talk about “Meeting the Unknown Self”.
Honestly, I would like to say that after watching the video, the first thing jumps into my mind is what Zhuangze said that it is not only about gourd (did you mean god?), but also our attitude towards the unknown self.
Personally, I believe (because you said "personally") most of people tend to examine themselves strictly by their experiences, refuse to change or make any progress in life. However, it’s the boundary of horizons that determines the way one’s thought. If our thought is tied down, we will die never knowing what a great person we might have been.
So it’s time for us to bring out our potential to meet the unknown self in our life.
As the proverb says, “All things in their being are good for something”, which means we need to transform the existing ideas towards ourselves to discover our new capacities and potentials. The most important thing is that we should not just complain about the environment we cannot change, because the most complicated part of meeting the unknown self is how to abandon our existing philosophy, which means change ourselves. I subsequently realized that the process to discover the reasons why we exist in the world is exactly Zhuangze’s wisdom of life.
So ladies and gentlemen, it’s high time for all of us to reexamine ourselves right here, right now.
Because a wise man changes his mind to pursue a better self, but a fool never will.
And that’s all, thank you.
