How do you handle fluctuations in form

I am a fairly low rated player. However there are days when I play like a champ. I have had games where on analysis the computer has said 0 inaccuracies, let alone mistakes or blunders. Very few such games, but still.

There are lots of games where I make some inaccurate moves at worst. I enjoy playing the board and things I do make total sense to me, I see lines of attack, I read the opponent like a book and I crush them. So it shows I am capable of playing well.

Then there are days when I just hang my queen and other pieces. The pieces don't make sense, I can't make sense of why I made one move when there was a clear better one available. I play like I dont know the game at all. Why the fluctuations in form. What is it that you do to keep playing at your best and just avoid doing stupid things.
