should i write my own ebook on making small profits?

i have a few ideas on how you can make some nice,not very big,but nice bits of money.Though im thinking it wouldn't be a very good idea really as most people are greedy and buy the ones which say like how i make $28 000 a month,which don't work and are scams anyways.
i have never written an ebook before,would i just need to make a few pages witha couple of pictures and text?i I would probably sell the ebook for like £1 but i don't think im gonna write it anyway,would anyone here actually be interested/what do you think

 

You'd be better off giving the information away for free on a blog and monetizing the blog. You'll get more revenue over time as it's not a "one shot" thing and you'll also have the value of everyone linking to your content.
