No, I'm not saying that I will staple water on to a tree, slam a revolving door, or eat my own head. You know, that type of dream or achievements you really really want, but it seems so hard that you think it is impossible. Aside from that, hello lovely people! It's me again. So I'm not that type of person who active on popular social media like Facebook, Twitter, Instagram, and other social networking stuff, so I get so lonely very easily. That's why I decided to make myself more active in this forum, haha. Anyway, back to topic! How do you know if something you want to achieve is impossible or just REALLY REALLY hard? Is holding on something like that necessary, or just forget it and move on?
