Silly blunders

Hi. I can do complicated tactics and i'm able to play very consistent games without big mistakes but i'm still able to make a terrible blunder. Sometimes looks like absolutely wrong move is sticking to me(mind trick). It has nothing with complex tactics but just silly one move blunder. I know that doing tactics makes difference but how many should i do to get rid of these blunders at all?

Example.

Thank you for your response. Unfortunatelly i didn't get your point and i can't find conclusion of it. I'm worried about blunders which happen when you are attacking with a piece like in my example. It's not like you've missed your hanging piece but when you are intentionaly giving it up with active move. Btw i didn't get your example game either. This game is very bad from both sides. It should be a beginners one.

I've made a similar mistake today. It was a king with a queen and i threw my queen supported by my knight between them to exchange queens. It would be working perfectly unless in the end of the day his king doesn't take my knight. I guess there is a flaw in my calculation if i don't consider that king is capable of such things. Silly but when i calculate fast i can make such mistake.
