You have to delegate. It can be a human or a robot. For example, make stock and use tools for social media content. Use IFTTT, Zapier, Make or n8n. Hire a freelance assistant etc.
Instead of saving money, don't stop using paid tools! Today I'm getting the top package on the automation tool IFTTT, and my mind is at ease. I'm kicking myself that I wish I hadn't saved money earlier. Using tools that save time and energy increases lifespan. :)
