"Rise and rise again, until lambs become lions." I heard this quote in the movie Robin Hood recently. It means "never give up" or it can also be translated to "keep on pushing until the impossible happens" (by Faith). In the movie, overthrowing the government of England is regarded as an impossible task and Russell Crow uses this quote to encourage his band and himself. For me, be focus and keep pushing the boundary of my research area is the most important thing right now. It seems easier, right! I don't think it is impossible if I try harder. So, never give up, no excuse, and no regret.
