Do-it-yourself (DIY) projects have financial, physical/mental health, and social advantages. Financially, DIY projects often cost less than paying professionals since labor costs are eliminated, and skills learned can be used for future projects. Physically, DIY projects can improve fitness as they may require exertion without noticing. Mentally, they keep the brain sharp by requiring creativity and resourcefulness. Socially, DIY provides an avenue for like-minded people to connect and discuss their projects and results.
