Do you have one or more computers available to use for learning software, Operating Systems, and networking? If not, I highly recommend having one dedicated for this purpose. There are lots of jobs for people with technical skills. Whether it’s DevOps, Modern Application Development, Network Administration, Virtualization, Network Engineering, End User Computing, Cloud Computing, Hybrid Cloud, or anything in or around these industry skillsets, there are high-paying opportunities waiting for those capable of proving their value. With the massive resources available to us these days online, you can take an old computer, learn how to install Linux on it, install a variety of development tools on there and start following tutorials, blogs, etc… Case in point, this article/video combo is not intended as a deep-dive technical topic, just a showcase of what you can do with well planned hardware even after it has aged 10 years!!!!
