It can also be conditioned when we internalise voices such as those of critical parents, teachers and peers, as well as advertising that leaves us feeling like we're not up to standard. Ms Vertessy says this kind of thinking doesn't just occur before bed. This basically means our brains are really good at focusing on negative stuff, regardless of our positive experiences. This rather pessimistic way of thinking is referred to as the brain's negativity bias, which American neuroscientist Rick Hanson describes as "like Velcro for bad experiences but Teflon for positive ones". Mulling over how awkward you were at that party is likely your brain is assessing the "threat" of not being accepted. It's a similar story if you fret over social acceptance, as being ostracised is processed in the same area of the brain that processes physical pain. So if you find yourself agonising over blunders made at work, it's likely you are assessing your performance and looking out for your livelihood. "In hunter-gatherer times, and indeed now, if we weren't paying attention to the cliff or tiger ahead of us because we were distracted by a beautiful sunset, it could spell our demise," Ms Vertessy says. It may feel like your brain is tormenting you, but according to clinical psychologist Deborah Vertessy, we do this out of the primitive need to protect ourselves. So why does our brain seem to cherrypick these random, and somewhat negative, thoughts as we are trying to fall asleep?

I’m certainly not a pro when it comes to shading and there is a lot more information on the internet when it comes to shading, these are just my basic ideas.Just as you're trying to wind down, it decides to play a compilation of some of your most embarrassing, regretful and cringe-worthy memories on shuffle. There are many detailed youtube videos that address these two common issues. Also, shading does not only include the dark but the light as well which are referred to as highlights. I would also like to mention that shading is an important part of creating texture in your drawing so it is important to consider the material of what you are drawing and adjust and change your shading according to that (references/images help a lot). There is a common rule in art where colours shouldn’t be shaded with black and I follow this slightly but it all depends on your art style and how you want your drawing to appear. → using dark or saturated blue to shade a green colour → using a dark purple to shade a pink colour → using a dark red to shade an orange colour I really have no set rule when it comes to shading but whenever I have to pick a colour for shading, I first pick a darker colour of the same shade but shift the colour wheel a little bit for a different hue
