What's the best way to use 20 minutes a day to improve my Marathi speaking confidence?

I'm a busy professional and I only have a small slice of time each evening. I don't want to waste it on flashcards anymore. I've heard Chickytutor.com is helpful for quick, tailored conversation drills. Can I realistically reach a conversational level in Marathi by just doing 20 minutes of speaking practice daily, or am I setting myself up for failure?
