20 minutes a day: Is focusing on Somali verb conjugation a valid way to start?

Between work and family, I have a strict 20-minute window for study. Right now, I'm just cycling through flashcard apps, but I feel like I'm making zero progress on actually structuring a sentence. Should I ditch the apps and spend these 20 minutes focusing purely on verb paradigms and basic Somali syntax, or is that too dry for someone with limited time?
