There is no such thing as a ‘perfect’ school (or anything else): perfect for whom? for what? but there is indeed such a thing as students who are very happy at their imperfect schools.They are happy partly b/c their schools are a good fit for them, and partly b/c they have realistic expectations of any human institution.
To that point, it is NOT advertised that college is the “best” time of your life, and over the years I have noticed that the unhappiest students are the ones who fling out that charge. College is indeed an important, formative stage of life. It can be a great adventure. But who would want the years from ~18-22 to be as good as life gets, and to have all the years from 22-death be downhill from there??!
So, go back to basics. You had some say in the choice of this school (by virtue of applying to it), and unless it was the only acceptance you had, you actively chose to attend. Why? What were the variables that were decisive in that decision? Do any of them still hold true- that is, do you still want those elements, but have discovered that they are not as present at your current school as you expected? These are the kinds of questions that will help you refine your shortlist for transfer applications. You want the next landing to be successful.
