Boring summer

This summer, i don't join in the Green Summer campaign because i want to concentrate to study so as to get high mark. I want to learn Environment Engineering branch. I think i lost myself when studying university. It's very difficut for me...I want to get a lot of achievement but my ability doesn't allow me to do that. I don't know to do things in this summer, a few of my friends have joined in the Green Summer campagin, a few of ones have traved with family
