Some advice

I stumbled upon this while reading a blog.

- An hour of sleep before midnight is worth two, and an hour of work before noon is worth two.

- Always pick your kids up from school. That’s when they want to talk.

- Never let your skill exceed your virtue.

- Never take less than two weeks off when you have a child or for your honeymoon. Don’t let them talk you down.

- When you mess up, admit it frankly and quickly, and move on.

- Always do your very best in your job, but if you don’t like what you’re doing enough that you would do it for free, quit.
