When brainstorming for possible niche ideas, think of the things that you, your friends and family use often.
Get into conversations with people and you will be surprised how many niche ideas you get from this exercise.
Write every idea down and don’t bother about screening them just yet.
When you are brainstorming, have a target audience in mind; it could be people like you (e,g person 18- 85 with love for fancy cars) or a whole other group of people you have concern for (for example, seniors with disabilities).
Or you can just work backwards an first pick a niche that is interesting to you and then later determine what you target audience is.
