No one is denying it is a corporate problem too, they have the lions share of it; the only one denying responsibility here is you.
And you are (implicitly) arguing that you can’t put any effort in, because it’s either do nothing or it’s a full time job. This is nonsense. I go to this store once, maybe twice a month. But the latter only because it’s convenient. It’s not even remotely a full time job.
But also no one is saying you have to do everything at once. I even noted i’m still very much a work in progress.
The important thing is to try, rather than just throw your hands up and claim you have no responsibility.
