How people change another. Opposite always apply

My teacher just spent one hour just to teach us the secret of success, how to be open-minded, keep the positive thinking and filter out the negatives. At first, i thought it was just a waste of time, but after half an hour or so, he had not only taught me how to be successful, he found my dreams and i nearly cried after so many months. So many months that i forcefully prevented myself not to had a single teardrops on my eyes and yesterday he successfully failed my almost-complete mission and i found what i really really want out of everything. If i did achieved my dreams in future, he will be one of the top listed person who i really want to thank and never want to forget. Thanks teacher. :)

Sincerely,
