This is dedicated to all of you, including me, struggling with what you are doing, you have to realize one thing that now is not forever, the thing you are doing right now doesn't have to be forever, yeah if you are having difficulty to adjust your new regime it is not forever, or if you are preparing for an exam and lacking sleep, it is not forever, if you are struggling with any aspect in your academic or physical life, dedicate the next year or years to that thing, this is not the rest of your life, and after that you could go back to where you wanted to

so the lesson here is

now is not forever.
