Pray hardest when its hardest to pray? I dont think this means we should pray hardest when were in the most trouble. Most of us find it pretty easy to pray when we need God to get us out of a tight spot.
"Satan tries to limit your praying because he knows your praying will limit him."-- please don't fall for this! I'd much rather start off praying spiritually dry and end prayer rejuvenated with spiritual fervor than not to pray at all.
I know at least one thing is for certain: God loves me enough to have sent His son to die for me so that I may live with Him forever. That brings me joy and what other say about me doesn't matter as long as this remains truth.
