Waiting upon the Lord will always develop our trust to Him. He wants us to develop patience and trust. It is often so hard when you do not understand things that is happening, but what is most important is to trust.
A person who is trusting the Lord is not worried or affected no matter what people say or no matter what things are happening whether bad or good. A person is not trusting the Lord when he or she is worried about things. Now, trust the Lord and He will give you the desires of your heart.
