We go through life with many disappointments, unhappy about this or that, wishing things to be different. First of all, this world is not perfect; we are not meant to live in this sinful place forever. Secondly, God wants the best for us. If every single thing that happens to us is exactly what we've wanted, we would be so spoiled and not think about God anymore. What we experience is exactly what's needed for us to learn, to find God, and to grow spiritually ~ it cannot possibly get worse anymore. So let's be grateful for what God has given us.
A footnote. Of course, you could ask about those who are truly in dire misery. I believe that if they know God, they would agree with my understanding. This is why we need to evangelize the world, starting with those close to us.
