I’m kind of tired of my guys having low motivation and constantly complaining

so how do i cheat them so that they always have a high motivation and dont get all depressed and stuff

And how do i get it so that they wont degrade in anything

You could chance it so that low motivation is a good thing.
If you want You can use this band.csv I modded, I think it works, but in theory you should be careful not get there motivation up - but that´s not hard -
I haven´t tested it but give it a shot and remember to backup you original band.csv file.
