Selecting right niche for YOU, is all about your passion
Now and then I see WA members especially new ones ask If that niche is good and so on.
This is really important question, but it is always asked wrong way.
Instead of asking
"Is ... niche good?" you should ask "Is .... niche good for ME" and you should ask this question yourself!
To be successful in your Niche you will need:
Obvious one, you can't convince any one to click a link or make a purchase of item or service you suggest if you wont be able to proof that you know what you are talking about it. You will have to do a lot of research and follow news and updates related to your niche.
Another obvious one, you will need to be committed to achieve previous point.
Probably not so obvious one, but look on it this way, If you will try to do niche you have no passion about, you will have way more difficulties achieving both pints above.
If you select a niche what is your passion, you will have natural motivation to learn to commit and to be good at it. You will have no problems to show you passion in your blog and users will feel it and will know they can trust you.
Don't worry if at this stage you do not have much knowledge about your niche, because if you have passion, you will have commitment and after a while you will become a guru.
