True, but the real problem is if you are not enjoying what do you do, you cannot keep the same work in future. Most bloggers started their blogs based on high paying niche (in their non-interested areas) are failure in long run.Do what you enjoy doing and it is not like work.
I am sure that you can talk more freely about the topics that you know well.What blogging is actually? it's nothing more than writing what you think.I have seen many people starting blogs just by looking at the profit at the niche but they got nothing at the end cause they lack later the content that is needed to keep site up.
So always start with a interest topic.
Write a link worthy content. Avoid poor quality links. Use Word press.
When it comes to blogging, it has to be some topic that you enjoy writing on, only then you will be able to be creative with the content. Provide good information to the people for getting the best response. Avoid keyword stuffing and unnecessary anchor text links, the flow of the content should look natural.
Another idea is to post detailed tutorials on your blog targeting a keyword phrase that is not having strong competition, but is on a popular topic. This is to stand a good chance of getting in the 1st page of search results.
For example: how you did something, such as upgrading the hard disk on your game console. This way, you have the first-hand knowledge, and can take photos of the actual equipment involved. So your post will be more credible, detailed, and original compared to writing about something based on only online research.
