I think life is better lived when you do what makes you happy.
Now in my 30s, I can see that responsibility plays a strong role in the quality of life I prefer. I've learned that I can't simply seek pleasures without also seeking means to obtain them. Pleasures such as traveling to foreign places and meeting the locals there, dining out, purchasing clothes/items/goods that bring me joy, and having a place to call my own.
Sure there are things in life that are free - fresh air, love, peace of mind. But these things are not enough to afford me a sense of safety, a sense of accomplishment, and a sense of delight.
For that reason, I'm a big fan of careers that pay well and allow one to live the lifestyle he/she prefers :)
