Please explain this hadith. What is Imam trying to say?

"Tribulation has been linked to love of this world." – #Imam_Ali (as)

In fact this world always demands efforts to reach a particular goal. A single bite of food doesn't go to the mouth without effort and trouble. Especially the person who loves this world more than hereafter, he has to bear always tribulation because he will never be content therefore tribulation is linked with the love of this world and that is inevitable. This is the meaning I understood but Allah knows better.
