Open the network tab in your browser's dev-tools. Right click on any interesting request and "Copy as cURL." Now you're well on your way to using cURL to do something interesting.

I use both :-)

Wget to download stuff in an interactive shell (shorter, and I know its -c switch to continue interrupted downloads), curl for anything else.

I would also say both has it's place. Wget is the downloader, curl is for when I really need control over the request, headers, body and so on (so interactions with APIs, testing, ...)

I think I'm just young enough for curl to have become my habit (started web dev in the late 90s). I feel the same way about wget. --help every time.

I never got the hang of it either. I still prefer httpie for having a better syntax and better support of plugins AFAICT.
