I say, "whatever I want to do." At the moment, it is sabbatical and travel and learning a new language. In the second half of this year, I will be starting training for a new career that I may never actually work in, just because I wish to learn those skills.
We humans are interesting creatures. On one hand, we value our rugged individualism, our ability to do whatever and be whomever we want. Every person on this forum is neck-deep in a process of self-reinvention, and in a much more self-conscious way than most. We are all hyper self-aware. On the other hand, we care so much about what other people think of us, even people we don't know or care about. It's not enough for us to figure out what the "right" path for ourselves is in life; we feel we must convince others of its rightness, too.
When I was in my early twenties, I fought with my parents incessantly. I wondered, why can I not get my mother (in particular) to just see reason? If only I could explain myself well enough, surely she'd be won over by the irrefutable logic and rightness of what I'm telling her. Alas, 20+ years later, that breakthrough in insight has never happened. I understand now that it never WILL happen, because you do not convince others of a worldview based upon logic. They either buy into it in their soul, or they do not.
My mother is an emotional creature; I am, too. We've spent far too many decades subconsciously learning how best to push each other's buttons and react rather than interact. Now I don't try to explain my rationales to her, beyond saying, "this is what I want." If I can't make that breakthrough with my mom, who has known me for over forty years and has a vested interest in maintaining a relationship with me, what possible hope can there be of convincing a recalcitrant acquaintance to see things my way? And knowing that there is no chance of success, why would I even try?
