Technovation has a few categories that help guide teams in generating ideas and solutions to help the world and I think it's pretty complete. The categories are:
Equality, education, environment, health, poverty and peace.
Based on those categories, choose one or a couple, try to find problems that you can see in your community or in your country (the idea is that it's visible to you), brainstorm possible solutions and choose one!
If you need inspiration, you can look for videos of the teams in youtube, it's pretty cool seeing all the solutions they come up with! Good luck :3
