There are a lot of skills you don’t need. You can be happy and successful without knowing how to rebuild a car’s engine, program a web application, or replace drywall. Sure, these are useful skills to have, but they aren’t absolutely necessary.
There are other skills, however, that can’t be avoided – skills that tie into various aspects of everyday life, that are not only useful, but totally indispensable. For instance, you can’t get far in today’s world without being able to read or write. And today the ability use a computer proficiently is simply assumed.
