Friend you are right that we are not a very big scholars that we can have a lot of information regarding the every field keep in our mind so for writing on a particular topic which is not related to our field we have to made a lot of research first of all because at this platform we cannot convey the wrong information because it can spoils the environment of this platform because this platform is just for those users who convey the right information to other ones.

It is not wrong to say at all that we may get exhausted sometimes when we are making a lot of research because when we open some sites then there are different information and sometimes the wrong information wrong means to say that sometimes there is irrelevant information present in different sites and not relevant to that about which topic we are searching out exactly so this is also a big reason mental exhaustion.

The technique that you have provided to all of us is really helpful that we should have some a work of enjoyment and take some rest of some minutes to refresh in ourself to do work again with full of creativity and inspiration.

Success for you !!
