A couple quick fixes for you:
attend meetings that are held every two weeks.
Consolidate this. Use "biweekly" instead. Also try to put as many words as you can in the active voice. "I attend biweekly meetings" is more active than attending meetings that are held biweekly.

Should have a hyphen.
and also to advice students
Advice is a noun, advise is a verb. Take out the word "to" and use advise. Usually, advise is a positive word. I think I would rework this to take out the part about the distractions and keep the focus more positive.
It is said that ''there are many doors of success in life to which education holds the key''.
The quotes aren't really working for me here because it is more of a proverb than a direct quote. In American English, the punctuation goes inside of the quotation marks (but not in British English).
