Just do as Srila Prabhupada says ,No mental concoction.

“Service means you must take order from the master. That is service. Otherwise it is mental concoction. Actually, the servant requests, ‘How can I serve you?’ So when the master orders, “You serve me like this,” then you do that, that is service. And if you manufacture your service, that is not service. That is your sense gratification. Yasya prasadad bhagavat-prasadah. You have to see how he is pleased. Now if he wants a glass of water and if you bring a nice glass of milk, you can say, ‘Milk is better than water, you take it.’ That is not service. He wants water, you give him water. Don’t manufacture better thing. Just like Krishna wanted Arjuna to fight, and he became a nonviolent saint, ‘No, Krishna, I’ll not fight.’ That is disobedience. Krishna says fight, you must fight. Don’t bring philosophy of nonviolence. That is nonsense. What He says, do it. That is service That he did later on.
Sometimes they misunderstand Bhagavad-Gita-gita, that Arjuna is not willing to fight and Krishna is inducing him to fight. They misunderstand that Arjuna is better than Krishna. But that’s not the fact. What Krishna says, we have to execute that. We should not manufacture our own ideas. That is not service.”
