And no, I am also not recommending anyone to become a trouble maker or anything along those lines.
Like most terms these days, they have multiple meanings and require appropriate context to interpret properly.
The type of Fire Starter that I am recommending you to become is:
An individual who is flexible in their thinking, promote the importance of sharing ideas, and empower others to open up and speak up.
I highly recommend you to read the article titled Become a Fire-Starter at the Office by Sandi Coyne-Gilbert on the Goodwin University website. If this is the first time you have heard of the term Fire Starter being used in this context.
If you decide to become a Fire Starter, I recommend bringing along another person on the journey, it will make the journey so much easier and enjoyable.
The path of a Fire Starter is not easy. You will face a lot of resistance and a lot of personal attacks. But like the saying goes: with great risks comes great rewards.
Good luck on the journey and remember, the journey is also a part of the experience. Enjoy it all.
