Accepted Answer

Well, laravel follows `PSR-4` so you should place your traits in:

`app/Traits`

You then need to make sure you namespace your trait with that path, so place:

```
namespace App\Traits;
```

At the top of your `trait`

Then make sure when you save the file, the file name matches the trait name. So, if your trait is called `FormatDates` you need to save the file as `FormatDates.php`

Then 'use' it in your User model by adding:

```
use App\Traits\FormatDates;
```

at the top of your model, but below your `namespace`

and then add:

```
use FormatDates;
```

just inside the class, so for your User model, assuming you are using the laravel default, you would get:

```
use App\Traits\FormatDates;

class User extends Authenticatable
{
    use Notifiable, FormatDates;

...
}
```

And remember to dump the autoloader:

`composer dump-autoload`
