One of the perks of joining X-Team is the Unleash+ membership. Every X-Teamer receives $2,500 a year to spend on what energizes them. Many choose to spend a significant portion of that on self-education.

Here's a list of ten programming courses that X-Teamers have completed and that they would recommend to anyone interested in the topic, followed by a list of useful subscriptions and, for good measure, a list of other courses that X-Teamers have spent their Unleash+ budget on.

Disclaimer: while many of these courses are expensive, it's worth noting that many platforms provide discounts for these courses at certain points of the year. Udemy, in particular, is known for heavily discounting many of its courses quite frequently. As such, it might be worth keeping an eye on the more expensive courses listed below, until they drop in price.

"I actually think multiple people in my team took it when we were starting the project I'm currently on, since we use a lot of GraphQL and it's a really hot topic right now. Wes Bos is pretty great IMO (I ended up also subscribing to his podcast) and I learned so much with his advanced React course, which builds a fullstack app with not only great React libraries and technologies like Next GraphQL but also with some important topics like server-side rendering,"

Most of these courses are entry-level or narrowly focused, but they're good to dip your toe in the water if you're unsure about pursuing a particular topic.

Other Courses

X-Teamers don't just spend their Unleash+ budget on programming courses. They also use it to learn how to trade stocks, learn German with Rosetta Stone, learn how to best capture light with a camera, how to play the electric guitar, how to play tennis, or even how to start your own forest garden.

"The Online Forest Gardening Course has been a huge help to my wife and me in planning our small scale forest garden. 15 online videos of various topics from designing the layers of the forest, to plant propagation, forest garden fungi and soil fertility. Loved it, and will be going through the videos again as a reference when needed."

There's no limit and no budget cap on courses to spend your Unleash+ budget on, because we're convinced it's enormously important to keep pushing the boundaries of your knowledge.
