You'll maxke more money if you can do the hard stuff that only a few people can do.
In computer science, there are some jobs that are easier to do and some that are harder. You can tell which are the easier jobs because more people are doing them and those people are being paid less. (Imagine you're an employer with a small budget looking at 100 people who can do the job...which one will you choose?)
The harder, higher-paying jobs are done by those with rarer, in-demand skills. (This is something you can verify yourselves. Search for news stories about "cobol" programmers) (It goes without saying that if you can do the hard stuff, you can also do the easy stuff)
These days, it looks like there's gonna be a lot of competition over the next decade or so for jobs in "data-science" and "web-publishing", so let's learn hard stuff that isn't those things.
There'll be less competition (and so higher pay) for the rarer skills that have been in demand as long as there has been computer science; Those skills involve the ability to make a computer do exactly what you want it to do as fast as possible, using as few resources as possible - and that is programming and software development.
Another, more general, skill that's always higher-paying (if you are good) is Product Development.
If you choose, you can use the G4G projects to sharpen your product development skills as well as both easy and hard software developer skills.
And the only way to become a software developer is to (no surprise) develop software.
So, do the work to get the skills! Start with Project 00: Setting Up.
What you won't learn: how to put together kits that have been designed by someone else.
What you will learn: Essential System Administration, Software Development, Product Design, Debugging and Maintaining Code.
BUT... These projects are not the typical ones! They are more interesting, and more fun.
AND... If you wish, they can be the basis for things you can sell.
AND... If publish your abilities where employers can see them, they will see that you can do the hard stuff.
