Sometimes when you're in the gym you just need to take the time to have fun, mess around, and enjoy your workout. I know when I workout I'm always pushing myself 110% always trying to go as hard as I can, and I'll find myself disappointed when I'm not making progress. Things shouldn't always be like that otherwise you could end up getting burned out and bored; don't be afraid to step out of your normal routine and experiment with exercises and equipment that you haven't tried before.
Just the other day I was having a bad workout, I wasn't feeling well and it had me frustrated. I was going to leave the gym when I started to talking to some buddies and messing around on a bosu ball. I ended up doing a whole workout with the bosu ball and had a lot of fun! Don't be afraid to stray from the beaten path.
