How do you actually “get good” at Fortran?

Hi guys,

Sorry I know this is a really basic thing to ask you about but I've been thinking recently about expanding my programming skills.

I was hoping to maybe get into Fortran but I have to admit it's very daunting trying to find good materials to start learning. My biggest issue is dedicating myself and being consistent so if there’s maybe a way to reward hack myself with coding exercises that would also be good

Are there any resources you'd personally suggest as a good starting point? I don't mind books, courses or websites really. I have a general preference for good quality textbooks so I can use them as desk references etc so if you had any suggestions that would be great.

Thanks
