Nobody Is Perfect -

In our universe, no one is perfect. Everyone has flaws and mistakes in their own right. But if someone calls himself or herself perfect, it is his or her ego that drives him/her forward. You don't necessarily have to be perfect every time. It's good to be imperfect. But the main thing is to accept your mistakes and work on them for better improvement. And this is what is called self-cultivation. Revolutionary movement for your own self.
