Time Management and Illustrator Patterns

I'm really struggling to manage everything at once now. I'm almost finished PPD but I'm baffled about WBL. It doesn't make any sense to me. Hopefully these projects are out the way soon so that I can concentrate on my Final Major Project.
I'm a bit apprehensive about using Adobe Illustrator as I'm aware it will take me longer since I have such little experience.
However, I have found this YouTube video by Howard Pinsky which shows how to develop a seamless repeat pattern. It helps that the pattern can be saved as a swatch to use again or layer over fills. This pattern tool, unlike on Photoshop, allows you to alter how the pattern is aligned.

The video gives me inspiration for how to develop a pattern using a single motif which contrasts to my current development of conversational prints.
