I am proposing a recipe of another kind. How do you create an interesting human?
Take a human who is willing to become interesting- this selection is an important part of your success.
Add some good habits. Reading is essential, others can be added as per your choice.
Add a taste for music.. of any kind. And a sport, again of his/her choice.
Expose to different people of all age groups.
Add a high level of curiosity, and a dash of speaking skills. Some listening skills too.
Some social grace for how to behave (kindly?) with others in society.
Activism is optional.
Add a generous dose of SMILES, and a sense of humour.
You are done! Serve to society at large, unless you want to keep him/her to yourself!
