Jika Bukan Kita, Siapa Lagi?

I like a slogan, "Jika bukan kita, siapa lagi?" "If not us, who else then?" This slogan is from an advertisement of Dettol. I can't find the real video of the advertisement, but I found a video with Dettol. (klick the link)
It always becomes my spirit every time I wanna do something. If we want to have a change then we can't wait someone else to do it. So, I always tell to myself, "If it doesn't start from me, then who else?"
