What does successful living look like to you?
Perhaps you are knee-deep in a career you love and you want to move ahead in it—or you're exactly where you want to be. Or maybe your career isn't the important thing but your relationships and social circles define a good life. Your job is just a job.
Or you might be retired and find that volunteer opportunities and more time with family and friends enriches your life. To you, that is successful living.
Your view of a good life is as different from that of others as your fingerprint. And we each get to define it for ourselves. What's important is that you are authentic about what makes your life good and what makes you happy. Then do what's necessary and possible to make it happen.
It's all about choices. You don't always get everything you want. But it is important to think about what you want and create a lifestyle that includes enough of those good things that you are content and joyful. If you don't have a goal in mind, you surely won't reach it.
If it's right for you, create a vision for your life—complete with as much detail as possible. Dream a bit. Later you can see what's practical and possible. Have fun with it. Then go for it!
