Ni hao ming , Yes you can grow fond of learning. If you acquired some knowledge about a language and you enjoyed the results, such as being able to form sentences , to communicate with natives , to read etc ,that will make you more eager to learn more of it to enjoy the benefits of what you have learned .

Passion is a love. If you love what you do, then you will get success on it eventually. Before you can be passionate of your learning you must find a way how to appreciate it.
