Make sure you have a schedule for learning a language. By setting up half an hour each day (or at least 10 mins), you will make progress much faster and see the results.
By setting targets, you can easily track your progress. For example, you want to finish A1 by next month or you promise to learn 100 new words in 2 weeks.
Don't forget to look through the content you've already learnt. Repeat words, use them as many times as possible and try to form new sentences with them.

Schedule 10 minutes a day in your calendar (or one hour per week) and follow the plan. This will motivate you to keep learning. Try not to miss your study times.
