My personal recommendation is to start a school
Step-by-step explanation:
Starting a school may at a first glance give an opinion that it is something not new. School is not something new but the implementation and reach out can be made creative.
Reason for choosing "school":
- Reach learners who already possess creativity and only thing you need to bring it out
- Smarter than the current generation
- Learners have ability to think out of box
- Best service to the world
- Can do hearty services to the poor and needy
- Eradicate illiteracy from the whole world
The how part of it is you need to decide and bring out your own creativity.
