How can we offer all the results of our work to Krishna?

From Dheeraj

In this quote

“If, however, you are unable to work in this consciousness of Me, then try to act giving up all results of your work and try to be self-situated.”

What it means “giving up all results of your work”, how can we give up the results…By donation, or by doing service to Krishna? the more we get involved in material activities the more we get attached to the result.
