I don't think any individual would agree that statement true about themselves. You may see there life as less in suffering but they don't.
For example I consider myself very happy now, but I have suffered greatly to this point and I will still suffer greatly in the future. I just deal with it better, not that I don't suffer.
I think that truly depends on the amount of suffering that you are under. What exactly do you constitute as suffering? Being bullied? Loss of a job? Loss of a loved one? I think if that is your idea of suffering you haven't suffered to the extent that people that truly suffered have. Have you ever heard of wilsons disease? It is a debilitating disease that destroys your liver and brain. Symptoms range from Chronic severe depression, psychosis, bipolar disorder, schizophrenia, difficulty speaking or thinking, difficulty walking, fatigue, involuntary shaking, no appetite, worsened ability to digest foods and uptake nutrients, and their is more believe it or not.
Go over each of those symptoms and try to honestly, realistically imagine yourself living each and every day like a helpless infant, but your a full grown man. Your minds still in tact and you fully realize everything that is happening to you. Imagine wanting to blow your brains out every day, but simply being too far gone to even make it to the store. Then imagine one day you just die because your body gives out on you. Imagine how dark that life must be, and you live it every day until you die. Every waking moment is a nightmare. Every time you open your eyes you are filled with dread that you are still alive.
There are no friends, there is no prom, there was no highschool or college, there is no wife or kids, the only family you have can't bear to even look at you. There is no goal or hope for tomorrow, there is no looking forward to anything at all, because nothing causes you any sort of happiness. Everyone you ever knew has passed you by, while you sit all alone as the years pass you by, but you can't even cry because every emotion that you ever used to feel no longer exists within you. Nothing about the person you used to be even remains, you are now a lifeless, worthless, shell of a human being just waiting to die.
Find me a reason for this kind of suffering.
