There's an easy shortcut to creating a product other people will love— Build something you would love.
Over the years, I've realized, as a solo founder with a limited budget, the process is much more important than the end result. And realizing this is a journey that can take years (which it will), I only choose to work on things that genuinely interest me in the long term (while also having the potential to generate revenue from the start).
Hence, the approach I use in all my endeavors is building products I would want to use myself, a.k.a "Scratching your own itch."
