Why would it be difficult? The only Google service I use occasionally is YouTube and I can do without, honestly. My Android phone is free from Google stuff and I use DuckDuckGo for searching since it launched. I pay a small subscription fee for my email and cloud storage.
And then I ran out of things I know people use Google for. Aside from YouTube (in EU and US) I am certain you can easily do without them. People just choose not to.
Because of work. I'm a software developer and one in a while I'm forced to develop stuff using Google software. Also developers search the internet a lot to speed things up, you can use an alternative for Google but usually not getting the best results. Now I can live with that, but my boss doesn't like it if I take more time to finish my work just because I refuse to use Google :p
As a software developer for 20 years who hasn't used Google in roughly 14 years, I can assure you that you don't need it for development or looking up stuff :-). Give it a shot, do without for a week or two; DuckDuckGo works superb and the main reason most people think other search engines are worse is because their Google profile is trained to find stuff they tend to click on, like Meta does.
When your employer uses Google software in development there's obviously not much you can do there.
