I have always believed that good education combined with the necessary experience equips one with the right attitude, freedom and confidence to face the world and its challenges.
Who doesn't!? It's a statement of the obvious. "I believe" often makes a sentence weak. It is usually better to not include "I believe."
Even if you don't include "I believe" it is bad to start with a statement of the obvious.
I think that first paragraph is worthless. It doesn't say anything significant or unique. But you obviously write very well! I don't want you to think I'm criticizing you; I'm just telling you not to start a piece of writing with general, obvious statements that no one would disagree with. Intrigue the reader.
"the mere thought of discussing things with the experts"---- this is very general, too. How about we fill this essay with discussion of the principles of advertising, the professionals whose work you admire, and the role you see yourself playing in the future with (what kind of?) company.
Also, no more 2-sentence paragraphs! For good composition, fully develop each paragraph.
Also, start with an interesting point in the first para, and then make that same point again in the conclusion to reinforce it. In writing, we use a rule that is also used in advertising: Say it, explain it, and the say it again.
