Learning Japanese? Take the train/bus/bike and listen to lessons via audiobook, listen to Japanese music, etc
Working on hygiene? Add your habits together in bulk. Do your face care, teeth, etc all together. Position all the products in a line in your bathroom drawer or countertop in the order you expect to use them.
Need to exercise more? Schedule your exercise with something you already have to do (going to the grocery store, walk or bike) or are highly motivated to do (go play DDR, hit the climbing gym, or listen to a video game podcast or 4 while running)
Remember that you are human and have a limited amount of willpower. So don't leave your goals to willpower, make them happen because they have to along the everyday journey.
