You enjoy learning Mandarin more when you accomplish more.
But accomplish more doesn't mean that you suddenly speak fluent Mandarin next week or next month. Accomplish more means you set up many many smaller goals and then achieve those small goals. Every step is an achievement, each week is a time to celebrate. Thus you get yourself into a habit of accomplish your goals.
You should feel good about yourself on every small step you made. You should be proud of yourself on every small goal you achieved. The very next small step is all you need to concentrate on, and this small step is very achievable as well.
In doing this, there is only one ultimate result in front of you: success.
