You won’t know until you try bunch of different things. And then you will have a handful of things which works and rest as failures.
And sometimes what works won’t be something you will be passionate about. For example, you may want to earn money – you try writing and teaching. Writing gave you money and teaching didn’t. But you were passionate about teaching.
Life can bring such dilemmas. And you will feel scared to jump anywhere. But remember what you want – if you are short on money then go write more.
Yes, that wouldn’t be as passionate but at least it will give you the cushion of money. And once you have that, you can always teach on the side.
Make the best of both worlds. Keep trying new things though.
