mindset shift - every encounter as an opportunity to practice the language. The grocery store, the bus stop, shopping at IKEA - whatever the circumstance where there are other people, go do the thing you were going to do, but also have an objective to have an engagement of some sort with somebody every time
This is a great suggestion and you can also call customer service of your bank or any other bank, dealership, grocery store, or any other service you are using. If you can do it in-person even better. With each passing, compare - how well you are getting understood.
