My chipping is by no means amazing but I found that my biggest improvement came when I started to enjoy chipping and not fear it. Practice it, practice it some more and then practice some more, try different shots but enjoy the good ones.
I don't usually fear it, kinda the opposite, I'll chip from a foot off the green where the conventional advice is 'a bad putt is better than a bad chip', practice it a bunch too...
But today I just kept thinning them, over and over and over again. I know it's just a 'off day' thing and I'm sure it'll be fine tomorrow
