I know that there is nothing better for men than to be happy and do good while they live.
God has given us the ability to take responsibility for our own happiness. Usually, we let our happiness depend on other people and situations, when in reality, God wants us to find our happiness in Him. There are so many ways that we put unrealistic expectations on people and rely on them to keep us happy. When that person moves away from us or when we are in a situation that we find uneasy, it makes us sad and maybe depress. God wants us to look to Him first and rely on Him for our happiness.
