The cure for impulsiveness?

Not related to your question, but did you consider 9. g5?

Hello and thanks for the reply. Do you mean g4? Yes I looked at it but it give black the two bishops and weakens my kingside so I don't think it is good.

You are right :) It looked better to me at first sight

Analysing your games and solving puzzles can help you get in the habbit of taking your time. A slow move will have the same effect as a fast one.

SIT ON YOUR HANDS DURING THE GAME!!

yes Yaroslavl, i have tried that but have difficulty moving the pieces and writing my moves down when my hands are under my buttocks

I am certain you can work around that.  Besides what is more impotant.

There is another aid to cure yourself of making impulsive moves.

Write down, memorize a checklist and title it:

Before I Make A Move Checklist  (Check every item on the list 2x before making a move)

1. What is my opponent's threat, and is there an indirect defense to the threat?

2. Remember Pieces can move and capture backwards.

3. How did my opponent's pawn move change the pawn structure of the position.

4. Have I looked for a better move than the one have found?

5. Does the move I have selected  KILL COUNTERPLAY of my opponent?

Thanks yard, I will work on that list

Red hot burning shame after you make a huge blunder is a great start (I should know).

Mostly, exercise the mindset of putting yourself in the opponent's shoes.  As soon as he sees your move he's immediately going to check if it's a blunder i.e. find everything wrong with it he possibly can.  You probably spent the last __ minutes looking at all the good points of your move.  Now before you make the move, beat your opponent to the punch by imagining your move on the board and finding why it's trash (so to speak).  All forcing moves*, every time, punish the hell out of your move, because this is what your opponent will be doing.

After the most punishing, impudent, annoying, scornful reply you can find for your opponent, if you still think your intended move is good, go ahead and make it.

*Forcing moves i.e. checks, captures, and direct threats
