Remember that reflection period after your break up? Well, it should come in handy now. When you're with your boyfriend again, remind yourself of what went wrong and try to prevent it from happening. If the problem was that you fought too much, then remind yourself to calm down when you have the urge to pick a fight.

Of course, if any fond memory of the past comes up, you should talk about it, but think of everything as starting anew. You're starting over, and this time, you're just going about it with more foresight. It's important to work on yourself to improve your relationship as long as both people are doing the work. But you shouldn't change yourself completely just to fit some image of what your ex wanted from you. You should only change if you want to change, not just for him. Remember that he liked you for a reason originally, so if you change too much, he may not be able to recognize the girl he fell for. There's a difference between addressing your flaws and being a new person entirely. It's okay to address your flaws, but... 

Now, please write a short abstract for it in Vietnamese. Abstract:
Không nên phạm phải lỗi lầm tương tự. Tránh gây áp lực quá mức cho bản thân. Bắt đầu một cách mới mẻ. Đừng quên là chính mình. Biết rõ khi mọi chuyện không đem lại kết quả.
