I think TASM, isn't that difficult. I remember learning this in a university course and I actually quite enjoyed it. There are youtube videos out there.
But to be honest, just approach it like any other language.
- Learn the basic constructs (control structure patterns, loop patterns and instructions etc)
- Use it to solve easy problems (something like the easy problems in project euler)
- Just read source code to see how people use it in c/c++ programs.
In general TASM is pretty limited, but the knowledge you gain there can be used in other places which makes it worth it.
