Dear beginning-of-the-semester self,
The past three months were pretty good, like you said time flies. Before I knew it the semester is over. I have learned a lot about college and about myself as well. I achieved my goals and I am excited to set new ones. I do not have a clear idea of whether I want to still pursue mechanical engineering, but I am still looking into my other options. I will still stop from time to time to appreciate where you are and how far you have come.
