What is the meaning of "a roll up someone's sleeves attitude"?
Like:
I must have a roll up my sleeves attitude.

Question

Answer

You need to roll up your sleeves and muck in, rather than just telling us what to do!

'Muck in' = colloquial. To help others to do something.

Answer

It means to actually do the work rather than just talk about it. For example, in a business, you might say a manager "rolled up his sleeves" to mean that instead of asking the employees to do it alone, he also helped on a project.

Answer

I agree with Nicholas’s answer.  Relatedly, it can also mean “a willingness to work hard”.
