This is probably the worst thing you could do to yourself. It doesn’t solve the problem if you don’t know what you’re doing, nor does it help you become better at what you do.
Pretending you know everything there is to be known only shows your unwillingness to learn from others or to be taught; to be open-minded about other’s point of views, ideas, or even solutions.
Some people’s ego and pride are too big to accept what they don’t know and learn from masters.
Make it till you actually make it, instead.
