I'd say skip step 1, there is lots of cheap and better UI design tools out there (see Sketch, Figma, et al), and they are very easy to learn.

Start by trying to replicate UI designs in the wild, it is incredible helpful! It helps you develop your taste and understanding of relationship between different elements, spacing, layout, grids… soon enough you start to see patterns emerge, which you can use when working on your own designs.

Focus on learning typography: it’s no secret that UI is mostly typography, if you get it right that is the job! Get a good book such as “The Elements of Typographic Style” by Robert Bringhurst – although is focused on print design, the core principles are transferable to digital.

Hope that helps!
