Scientist and Innovation

I'ts really hard to be a scientist.First test will never be a success.But the first attempt always lead to the second third and so on..FAIL always bring to SUCCESS!But actually i'ts really bitter ti taste the sweet.It's not easy man!Needs the strength and patience just to feel "YES!I've made it!"Exhausted~A usual thing of being a scientist.Owh!Don't know what else to say..daa
