It means that life itself is made up of challenges; that to live is to experience problems.
You don't you just go with it.
Anything with mass will resist acceleration. So says Newton, and he's right.
A thermal insulator resists heat transfer and an electrical insulator resists flow of electrons.it is heat,light,antiond mo
