If you're struggling to get yourself into gear today, why not kickstart your brain with a tricky optical illusion?
It features 11 rows and 20 columns, mostly consisting of the letter 'M' - however there is one 'N' hidden amongst them that keen-eyed viewers are challenged to spot as quickly as possible.
This brain teaser tests your observational skills and only those with a high IQ are able to complete it quickly, writes the Mirror.
According to JagranJosh, those who have a "high IQ" will be able to spot the odd letter inside 11 seconds.
If you've had a look at the image and are having no luck, here's a helpful clue: you will find the 'N' somewhere on the left side of the illusion.
If you're still struggling, focus on the first five rows of the image - be sure to carefully look at each row one-by-one.
You can scroll on to see where the odd letter is located, but consider this a spoiler warning.
