I remember years ago hearing the mantra:

Fail fast and fail often

But here's what they don't tell you about failing - It only helps if you actually learn something.

Here's an example: Let's say you launch a LinkedIn paid ad campaign for the first time. And it flops (true story).

It might have been because of the image,
or the copy,
or the offer,
or the targeting,
or the timing,
or the channel,
or something else ....

You just don't know.

Now, let's look at a different way of doing it.
You split-test multiple LinkedIn ads in parallel, with variables that are different between them so you can see the impact of each variable. Or you try on LinkedIn the exact same ad that worked great on a different social network.

Now you'll learn something, regardless of the results being good or bad.

So before doing something, make sure you'll learn something even if it flops and ask yourself "Will I know why it failed?"
