Many people assume that Stoics are staid and cheerless people, never smiling or carousing, or ever having any kind of fun.
But that is misunderstanding what it really means, to be a Stoic. Stoicism is all about being satisfied with what one has, or in fact, being grateful for all we have. If we are alive and not in pain, we are so much better off than someone who is alive and in pain.
If we have shelter and food, we are better off than a homeless person with no access to anything to eat. If we have a job that we get paid for, even though we’d like a better, higher paid job, we are still better off than an unemployed person.
If you were to think on the good things in life you have, and imagine how you may be if you didn’t have all of those things, you will see that yes, you do indeed have a good life. And if there is someone who seems to be having a better life than you, what of it? There may be negative things happening for that other person of which you have no knowledge.

Life for me is good. I have a roof, a husband I love, who loves me. I have a fine son, and other family members I love, and who love me back. I have a dog who brings joy to my life. I have a garden with beautiful flowers, I have food growing in my garden too. And that blue sky in the photo is up there above me on most days. Beautiful!
I am a very fortunate person. I can honestly say that, and I believe. I can imagine many ways in which my life could have been worse, and indeed still could be worse. But there is no point in getting upset about those other ways, because the life I currently have is the only life I can have, the one I’m living right now.
My future life is truly unknowable. I could guess at how it may be, but I can’t live it, until it is here. The future is a myth, and while some things can be prepared for in the present, there is no point in getting so carried away doing that, you neglect to proper ‘be there’ in the now.
These thoughts are from my own personal understanding on what Stoicism is about, and if I don’t get it quite how another person sees Stoicism as being, so be it. We are all entitled to look on life how we consider it to be, and live accordingly.

The link just above was the resource I used to write this particular, along with my own thoughts, based on my other studies, especially this book:

So are Stoics happy? Well I consider myself to be a Stoic, and yes, I am happy, are you?
