Show me the specific text in which Einstein stated it.
Not to mention that Einstein probably never said that.
He did, in fact, say that. OP is, unfortunately, misinterpreting the quote in order to fill his wanted definition.
In Runescape, you don't do the same thing over and over expecting a different outcome each time. You do it as a process to achieve something, such as a level, a drop, etc. Aka a shitty job.
I am far too lazy. And, if you actually cared, you'd be able to google it to confirm it or not. You're just trying to strawman. It's cute. Like a panda.
