It is not easy to receive critics of your work.
Definitely, it helps you to grow. Especially when it is constructive. By that i mean when person can explain why he/she thinks so. And i am totally for it.
But when you receive just written things people didn’t like – it’s harder. You start to think why and somehow it brings down. Especially, when no good feedback is there.
People should criticize you, but they shouldn’t be lazy to say why.
Always be wide in your thoughts, you help people to grow.
