Try do it, if fail, that's no problem

When I woke up in the morning, I suddenly thought that I really have to prepare for the study abroad after the graduation from university. I was first planning the use of summer vacation, and I was unsure about how to make it meaningful, but I got a hint that time. I will research about the experienced people's life on summer vacation later, and I think I will put best effort to prepare.
Things like TOEFL, GRE are the criteria for that, and that takes so much time to make them ready, so that I think I will do those thing this summer and make my situation ready to go study abroad. In that situation, I can decide whether go or not or which school to go with relaxed mood.
I do have a lot of things to do except for the preparation, but I have to do both, no excuse, I just do it. I will put 20% of time I spend for my main work from now, so that I will use it for the preparation. And in the summer, I will be serious, do everything. This summer is the last good chance for that.
This is for my mental health, if I fail to achieve my goal, that's not a big problem. I will just have a way to study at Japanese graduate school which is also good. But basically, no excuse.
