Remember that creative writing should always be considered as a fun-filled activity. This is why it is significant for you to involve games in your writing workshops as it would allow the students to generate new story ideas. You can try to indulge in the word game by letting the students think on contradicting words such as sky and leaves instead of sky and clouds or tree and leaves. This will boost their imagination and trigger great unique concepts in their mind. In addition to this, one can always step outside the hall or classroom and explore new things to develop story ideas. Keep sharing different kinds of challenges with the students and see how well they come up with different writing ideas.
It is highly important for the mentor to allow their students to try new things, for the world is full of new opportunities, concepts, and skills. Be someone who builds their confidence and grow with them in terms of team work.
