Success is a completely relative term. Gandhi was incredibly successful in my opinion, and he owned three sets of clothes. Bill Gates is also successful and he's worth over $50 billion. So the question, or standard of measurement becomes, what do you want to achieve in your lifetime, or how do you want to live your life? Then the degree to which you do is how successful you are.
I always think it's funny to consider what people mean when they vote for the "most likely to succeed." I received that designation once. I assumed that my peers thought that I would be the most likely to achieve riches or letters after my name. I, on the other hand, was most interested in becoming a really good mom. That was how I defined success. (For me.) I have achieved "success" in that area through a lot of very, very hard work and immense dedication.
I think it is impossible to define it, except for yourself. For me, it means being happy with what I have, but still trying to make things better for myself, my loved ones, and the world in general. Having good health, and sufficient material goods and mental stimulation :)
I believe that success is reaching your goals, whatever they happen to be. Some people want to run a corporation, and will not consider themselves successful until that goal is achieved. Others consider their ability to love others representative of their success. Both are correct.
I believe success to be the point in your life that you feel content with what you have and what you have achieved. Success can be achieved at any age, though many people may never feel they have been successful in life. In society money is considered by many to be the measure of success. If that is the case then why do wealthy people fall into drugs, alcohol or other destructive behaviours.
To achieve success, I believe you have to have goals in life, work hard and the rest will fall into place.
This is, of course, a matter of opinion.
In my opinion, success consists of getting for yourself the kind of life you want. This must be the kind of life you truly want -- one that will make you happy. For different people, success will be defined differently because different things make different people happy.
For me, happiness is having a happy family that gets to spend time together.
We have achieved success through education (having enough education to get a good job) and through some sacrifice (I no longer work full-time so that I can stay home with the kids).
But this will differ for different people.
Success, to me, is happiness. And happiness implies contentment. So, when I am happy, I unterstand that I have achieved something.
Success is different in each individual's vision. It is generally accompanied by a feeling of satisfaction and balance . Success can be achieved through constant pursuit of an objective and through much diligencence.
Success is being able to do what you want, when you want to do it. It is primarily doing what you love to do and making an enjoyable living out of it.
