These are called challenges because they are hard to accomplish, I have not mastered any of them.
You might ask yourself, as a good friend of mine once asked me: "what if the other person does not deserve your respect?". A valid question which took me quite some time to come to my resolution (yours may be different); you treat them with respect, not because they deserve it, but because the way you treat others is a reflection of yourself. Also, there are different levels of respect; something to consider.
This does not mean to leave things to chance or to behave in a manner which claims absolution from consequence. It means that you should recognize that giving power to your fears [especially in those situations where you find yourself with little or no control over the outcome] is a counterproductive practice which only encourages more uncertainty.
