It is important that you find a healthy balance in your life and take responsibility for your own health and wellness. Avoid nicotine, excessive caffeine, and other stimulants. While nutrition and exercise together don't prevent stress, over the long term, they can develop greater physical efficiency and make you fit and better able to withstand the strain associated with high levels of chronic stress. If you are impatient with long lines, don't plan on going to dinner at peak hours.
Good Planning can include time management, goal setting, life planning.
This is a proactive approach which can alleviate some frustrations in life. It may take time to plan but you need to evaluate if the time saved by planning is more than that spent without planning. When you have a personal goal, set it and work towards it. You will have a focus. Assertiveness and communication training is a vital tool in your personal self management.
