The state of nature has a law of nature to govern it, which obliges every one: and reason, which is that law, teaches all mankind, who will but consult it, that being all equal and independent, no one ought to harm another in his life, health, liberty, or possessions.

No matter what , just do not give up .Always believe that your dream can come true & just keep working for what you want to achieve.

科学没有捷径，只有脚踏实地。
