Kazuo inamori once said: Self-interest begets life, while altruism lasts for a long time.Keep an optimistic attitude and turn every ray of sunshine into motivation.Users don't care about products,

If you are willing to hold an umbrella for others, others will be willing to pave the way for you.

Money has energy, it is always in the head, not in the pocket.Altruism is an advanced self-interest.
