Here are some ideas.
If you use a tracking system for your work, you can use your completed tasks as inspiration for your next goal items. They are usually descriptive enough, and hold real value.
If you don't, the same applies. It's always useful to think of a goal as set of tasks. What steps will you take when preparing, for example, the infographics? You will need to do some research for the field (what type of research, where, for how long, what will you be focusing on while doing it, etc). You will also do mockups, and for them you will need assets. Where do you intend to get them? Do you need anything else to locate them? Then, will you be editing your assets? Do you need custom fonts? How will you get it revised? What about distribution?
Try to imagine your goal as a plan, and the descriptions as real steps you would (or will) take. Don't add noise for the sake of quantity, most people would be thankful to see a real, concise summary of activities and not four pages of nothingness. Also, if you have the chance, think about layout. Categorize your tasks by hierarchy or dependency (which ones need to be done to let the rest happen), mention technologies... if content is not your strength, then focus on shape and strategic organisation of your (limited but real valuable) information.
