Question requires far more detail.

If I had 100 kids, I'd put them to work doing lawn care + power washing, because I know they could succeed at these activities...

And... as important... these activities would get them off their phones/screens.

Having a "Digital Marketing" background... you already know how many lies + myths exist about the effectiveness of DM.

If you're interested in teaching them effective marketing, have them mow lawns + powerwash for a year, then teach the most diligent of the 100 about copywriting for email + direct mail.

As copywriting + list selection is the core of effective marketing.
