Problems without a manual.
There are two ways to go when installing something new.
Either you read the instructions first, or you don’t.
Those aren’t dividers for different kinds of people, they’re simply two different strategies when facing a problem. Either you do your research on beforehand, or you go with a trial and error kind of approach.
One significant thing to keep in mind when approaching a problem is that there might not be a manual. If you’re too reliant on there being one, there are only one type of problem you can solve — the IKEA furniture kind.
On the other hand, if you can solve a problem regardless of whether or not there’s a manual for it, the world will be open to you.
