Dear professor, there is no right words to express how grateful i am for all the knowledge and all the things you taught me. without all your effort to put me on the right path and your belief in me i would not be the person i am now. thanks to you that i have experience and confidence for my future achievements. i will never forget that. i am happy to realize i am not the only student enlightened by you and that you helped so many people in achieving their dreams. thank you for believing on me, i will never forget it. i wish you many years to come and many more students to be mentored by you. forever grateful, (name)
