I have a dream. How can I make it come to true.

Before I try to give a (hopefully) pertinent advice, i just have a question: how badly do you want that master's degree from tongji university? I feel that, unless you know how important that degree is in your life, you will not be motivated enough to study. You also have to make sure that this is the right time for you to take that master's degree because if you feel some form of reluctance or doubt, don't push yourself too much. Right timing is of the essence. For now, try to relax and clear your cluttered mind. If you'll be able to regain your focus and determination, I feel that you'll find it very easy to study hard. Further, try to envision yourself as a graduate student of the master's program of tongji university. While visualizing it, how do you feel? In other words, you have to be certain that you would be able to meet the rigors of such a program, once you're already in. But before you do that, you have to check your purpose or motivation first. Do you truly believe that your motivation in taking that master's degree from your desired university would be enough for you to ace the entrance exam of that program? If not, why? You may have to reassess your motivations. If you think that your motivation will easily make you pass the entrance exams of such master's program, try to ascertain whether such motivation will equally be that compelling to make you stay or make you meet the demands of the same program. This is of absolute importance because, getting into the program is one thing. But staying in the program is a totally different thing. Getting into the program requires good preparation and tenacity. Staying in the program, I feel, is much harder. It requires full commitment and bull-strong determination. Endurance is key. So, do you really want to be a proud graduate of the master's program of the tongji university in the future? If you truly do, then do what you have to do. Prepare now. Good luck, zhuker!
