This one sounds tough, but you don't have to be an engineer or tech wizard to take on the challenge. By following basic guidance and instructions, anyone can build their own computer. It's fun to learn what parts go where and why, and with having the ability to choose specific parts or components, your personally built computer is more than likely to out-perform one you would pick up at the store.
Get motivation and find support by joining an accountability group and surround yourself with people working towards similar goals. These groups are designed to increase your performance, measure your progress, keep you engaged, and allow you to express your thoughts and feelings. Search for groups through your social media accounts. Discover forums (like this one!) where you can share about your journey and receive virtual support from others going through the same experience. If you're feeling courageous, start one of your own!
