Your least critical stress issues are those with a low priority and are very difficult to change. For those stressors that you can change - develop a plan. For those stressors that you can’t change - than you need to change your response to them.
“ The most successful people are those whose success is the result of steady accretion. It is those people who carefully advance step by step, their minds becoming wider and wider, and progressively better able to grasp any theme or situation, persevering in what they know to be practical, and concentrating their thought upon it, who are bound to succeed in the greatest degree.” --Alexander Graham Bell
