### Do you have business cards?

#### Efrén Martínez on December 12, 2019

hello devs!!

I am currently developing my personal brand.

I'm working on business cards but I don't know what data to put. A suggestion?

I don't want to saturate information.

Greetings from Mexico :P ``````  #include <stdlib.h>   // card > aek.ppm

wow, impressive! :)

In many settings where a business card is "typically" required, I've found that people are open to just sending a blank email (or maybe a few words of context) to the other person as a dual reminder to follow up later.

It might be worth it to buy some business cards to have on hand, but I wouldn't go overboard with quantity!

I still consider not making so many cards.
