first hundred years are the hardest

first hundred years are the hardest

Prov. The first hundred years of your life are the hardest, and after that, you can expect things to get easier; in other words, your whole life will probably be difficult. (A jocular, ironic way to console someone who is having difficulties.) Don't worry; things are bound to improve for you. The first hundred years are the hardest.
