7 don't envy others' success, it is at the expense of comfort;
1 Don't envy other people's talents, which are obtained through private efforts;
4 don't envy the simplicity of others, it is cheating and open-minded;
Don't envy others' maturity, it is the result of experience and vicissitudes!
You can appreciate it, but don't envy it, because others deserve it!
1 and what you should care about is:
What kind of life do you want?
What did you pay yesterday to get today?
What will you pay for your tomorrow!
