Recently I picked up this LN and can't put it down. Someone save me *. Jokes aside, this is a really good LN, definitely worth a read. If you have reservation about reading LN, there is also a manga.
This LN is really popular in Japan and is basically what Konosuba is parodying. It's about a 30 year old NEET got hit by a trunk :P, and reincarnate into another world with memory intact, and he decide this time he won't squander his life and worked hard.
Here is the link to the Manga:

If you are interested in the LN, here is the translation. There is a link that allows you to download 1-24, you need a ebook reader for that, I recommend icecream ebook, it's free, it can only hold ten books, but all you need to do is delete the library and clean the recycle and you can read further.
