Kazuo inamori once said: Self-interest begets life, while altruism lasts for a long time.And care about what kind of value and honor your product can bring him.

Keep an optimistic attitude and turn every ray of sunshine into motivation.Know how to reflect on yourself and regard every setback as a stepping stone to growth;Users don't care about products,

Money has energy, it is always in the head, not in the pocket.And care about what kind of value and honor your product can bring him.Altruism is an advanced self-interest.
