When you have some success， the feeling of being an imposter can be real. Who am I fooling？ But when you create things that only you — with your unique talents and experience — can do， then you are absolutely not an imposter. You are the ordained. It is your duty to work on things that only you can do.
The human heart, at whatever age, opens only to the heart that opens in return.
我不是那种会让我的忠诚动摇的人。
