If you are stuck in a rut, you are in a situation that has become boring, unproductive, uninspired and weighed down, but that is too difficult for you to change.
people can also use in a rut without “stuck” where it’s impossible to make progress.
Let’s see other examples :
– I feel I’m stuck in a rut, both at work and at home.
– after 5 years working in this company I feel I’mstuck in a rut.
– At thirty my career was in a rut, so I had to change it.
