Why learn calculus?

This chart is hilarious because it’s true. We spend years clawing our way up the math mountain, only to find that the most useful skill in our jobs is… spreadsheets.

Marketing analysis

The image nails one big idea: relevance wins attention. Calculus might be impressive, but spreadsheets are practical. Great marketers do the same — they show people exactly why something matters to them right now, not someday.

Why it works

• It ties learning to real-world usefulness
• It reframes “boring” skills as super practical
• It uses humor and simplicity to make a big point
• It visualizes value in a way anyone can relate to

Examples

• Duolingo makes learning feel useful with daily streaks
• Notion’s templates show direct work-life relevance
• HubSpot teaches “how to write better emails today,” not “master communication theory”
• Canva promotes “making a design in 30 seconds,” not “learning graphic design principles”
