What do you do when the credit and praise for your idea or creation is given to someother?

Oftentimes, they garner the credit and have selective amnesia regarding the circumstances for the idea.
To me it is a stab to the ego, I have learned somewhat to accept it as an indirect confirmation, but it still gets me frustrated. This is not directed at this arena, rather towards thieves in the work environment, interpersonal interactions, family relationships, etc.
For example, my wife does some clever and awesome home interior decorating, the older sister pretty much copies it, but she gets all the praise. Or concerning an area I am knowledgeable about, or like to think an “expert” is asked for, but my opinion is largely ignored and replaced by a misinformed solution from someone else, with an undesired outcome. Or you start working with a new company, and provide valuable business resources they were unaware of that ultimately pans out, but you have to remind them to get any credit; otherwise someone else will run with it.
Maybe this comes across like I am some whining victim with a big target on my back which really is not the case as much as it once was. Then, maybe it really is just a dog eat dog world.

What do you all think.
woof!!
