Honestly I don’t know why anyone would consider it hard: you just stop eating animal products.
Maybe you have a different definition of vegan. Most say “vegan” means no animal products at all. It requires a ton of research to avoid constant minefields, because animal products can be in everything. Dyes, scents, preservatives, flavors, polishes, powders, etc… Even fresh fruit can be non-vegan, because sellers will polish their fruit with beeswax or shellac to make it more shiny, and give it a better shelf life.
