I look around my home & property, almost finished after 47 years of hard work, and I am content.
After a very turbulent & painful beginning to my life, it is Exactly what I both want & need....i consider myself RICH.

We all measure how successful we are by comparing to others, even subconsciously. Could we ever stop doing that, I wonder? Self-fulfillment is probably the ultimate success and happiness for everyone.

For me It's about your goals. If you wanna be a bum and succeed then your a success.

Just be who you are. Don’t be a conformist and don’t sacrifice your principles for any reason or for anyone. You are responsible for your own happiness, your own health and no one else. Others opinions are not your problem. You only live once, that’s it.

I'll get back to you on that. As soon as I am succesful.....

Success is an almost day by day, project by project thing. I sure like money, the security it buys, not so much the material things. Quite simply buying whatever I want in the grocery store with no financial worries makes me happy

To quote waitingforgodo below. "To achieve the stated aim is success."

But I think that it is true that there are some aims which are better than others. Therefore having better aims may be regarded itself as a form of success, which raises some successes above others.

At one end of the scale. If my aim is, to beat my wife without getting arrested, then if I can stop her phoning the police, I am successful. At the other end, if my aim is to help cure world hunger, and I succeed in finding a new crop that will grow in deserts, then I am successful.

Getting enough personal wealth to live a happy healthy life, is perhaps somewhere in the middle. But the big point about that is, that almost all studies made of the subject show that very little wealth is actually required for that. So that getting wealth beyond that, just for it own sake, and because I have not the thought and imagination to think of anything better to do with my limited time on earth, falls much further down the scale.

To achieve the stated aim is success.

If the aim is to acquire material things and it's achieved then that is success.

Is there a problem with accomplishment resulting in a modestly comfortable lifestyle?

Should success necessarily be conflated with a debacle of dissolute debauchery?

In the afternoon.

The first world is guilty as charged.

I once worked for a multi-billionaire and by the common yardstick of measurement he was very successful. However, most of the time he appeared thoroughly miserable and did not seem to enjoy what he had acquired.

I once did. But, I came to realize it as something entirely different.

Noooo. Material things do not mean anything if you are unhappy, depressed or ill, however apparently there is a cut off point to how happy one is. After earning $75000 per annum people are not happier if they earn more.

Nada, that definition of success is everything that’s wrong with the world.....

"To laugh often and much: To win the respect of intelligent people and the affection of children, to earn the appreciation of honest critics and endure the betrayal of false friends; to appreciate beauty, to find the best in others, to leave the world a bit better whether by a healthy child, a garden patch, or a redeemed social condition; to know even one life has breathed easier because you lived. This is to have succeeded."

No, I think success is more about relationships than achievements or material wealth, but my perspective is influenced by having more "success" at the former than the latter. It appears, from my experiences with online dating, that most women in my local dating pool, at least among the ones who are college-educated and professional class, that success is more about the latter than the former, and that they will only date men who are "successful" in the latter sense. Which is ironic, since all of them are divorced, and one would think that their top priority in trying again with another relationship would be someone with a good record in relationships, both with friends and significant others, but apparently the impressive resume is more important to them in who they choose for their next potential partner.

So, in my opinion, they get what they deserve, which, from what I hear, is usually another failed relationship.

It's a wholly subjective matter.
Everyone is going to have a different opinion.

Learning how to live without creating suffering for yourself or others.

Success is relative. As a younger man I would have wanted everything I could get if I was not so stupid at the time. Today as a single older man I'm happy and successful living in my 2 bedroom mobile home parked on my half acre of ground in the small city I live in. I work and also have social security, have what I want and do what I want. I'm not a rich man but I have a low mortgage. If the car blew up I would simply go buy another one.

It certainly does not apply to me. Being single, independent, non-violent, living by secular Humanist values is what makes me "successful". Your mileage may vary.

Happiness. have a roof and food....and happy? Works for me

Success is living a happy life.
You can be rich and miserable.
However most of us live quiet lives of desperation where we're not rich and we're still miserable.
