Post ideas that failed drastically

Hi, so this question is directed to all those other bloggers that I know are out there.

Do you ever have an amazing idea, then write it up and it sucks?

You know when you think "this is going to be sooo amazing" and then you write it and you basically made yourself sound like the world biggest idiot?

Or is this just me?

I do this so much.... here are some of my failed blogging ideas

History of nail polish
    That was just too boring.

My take on various slogans
    That was never going to work out right!

Styling 60's mini skirts
    This didn't work because I don't actually own a 60's mini, which was kind of a key part.

Pantomime review
    Cause your not allowed to take pictures at a pantomime so it would just have been me laughing at stuff and no one else would get why it was funny.

Kylo Ren fan thing
    Mainly because I thought no one would comment/share or think it was a good idea!

People getting stupid over celebs
    I might still do this actually!

Honey I shrunk the kids review
    I thought the movie was too old and it would be boring

10 things people thought I said but I didn't
    I got this idea after Jess thinking I said something totally different to what I actually did say.
The idea didn't work out though so I put it as number 4 on this post instead.

So is this just me who gets stuck?
I will see you soon with some cute pictures I took over the last few days x
