I understand life is very stressful, but it's not a sudden occurrence or unfortunate things happening to you or many others. Stress is part of life, a way of life, and if I can say, the essence of life. We can identify the root cause of stress, which is actually the problem, solve it, and then move or graduate to other stress = problem. So, life is about moving from one stress to another; the way you move will determine the quality of your life.
However, certain suggestions do work in reducing stress, but there is no magic potion to remove stress completely from our lives. My suggestions are:
To Each Its Own
Every single capable adult is responsible for his/her life, so don't take stress or tension for people around you, be it your parents, siblings, friends, or even adult kids.
Spend Less, Earn More
Keep control of your spending habits, spend only on absolutely necessary items, don't fall into the rat race of fashion, show-off, and comparisons. Maintain a humble level of austerity.
Keep the End in Mind
Finish the task before it becomes a deadline, avoid distractions.
Be Assertive
Choosing yes or no to anything is your right, not a privilege or obligation.
Believe in Destiny
Whatever happens, happens for a good reason, it's exactly destined to happen, and you or others are just playing by the script of life.
Do Charity
Give, give, and give. Food to the hungry, water to the thirsty, clothes to the naked, solace to tears, company to the lonely, knowledge to the ignorant, appreciation to the forgotten, laugh to the frowned.
There is no best recipe for a perfect life. Live the moment, live it now!!
Happy Living!!
