For instance, personal finance is a hot topic right now. Thousands of online venues publish news, analysis, and advice about investing and money management. If you write about personal finance topics, you've got plenty of stiff competition, so it might be difficult to break into attractive online markets. Therefore, it might be a good idea to try to get work writing about personal finance for a suitable but currently under-served audience. Covering personal finance for seniors may be one potentially lucrative option.
Seniors are one of the fastest-growing online audiences.
Their personal finance needs are quite different from those of people in their 20s, 30s, 40s, or even 50s, but currently there is relatively little information published to meet their needs. You can have more than one focus, if you like. You can be a movie reviewer and an education writer. You can write about origami and horse training. Or parenting and backpacking.
