@Elmud,
Good questions, good issue.
First off, I don't think it's necessary egotistical to declare yourself an 'artist'. It's not saying that you're
great or even
good; it only speaks to where your interests lie.
Next, the whole issue of resolving the practical necessities of life (i.e., a career or vocation that earns you money) with where your interests lie is a tricky one. I, like many people, ended up choosing a career that was distinctly different than where my interests were; this was out of practical necessity. But yea, some folks are able to
become what they always wanted. Again, in my experience, this is the exception rather than the rule.
I think one is best to try and
balance the two; the need for a vocation and the desire to achieve-X. If you
can meld the two; yee-haw. My son is actually working through this entire issue right now (my youngest, he's 24 now). He too wanted to work in the movies and has discovered its overwhelming improbability. It's starting to set in with him now that "real life" has "real needs"; food, clothing, shelter, etc.
As far as the general question: How does one discover their purpose, their destiny? I'd offer the following from my own 'meandering experience'[INDENT] First, I'd suggest that there is no
single path that's 'best' for you or anyone else. For either interests or career there may be
multiple combinations that'll work. I used to believe that 'out there', there was One Job/One Wife that was just waiting for me. I've since realized that there were
many possibilities; that which of each I ended up with was a matter of choice and circumstance - some no better than the other.
[/INDENT][INDENT]Second, I'd place the highest premium on the 'practical' necessities. If you're in a situation where now (or later) you'll need to earn your own income to survive, that this should take priority. There's nothing wrong with pumping gas or delivering pizza's to make some cash. If; however, you can work in a vocation that is one of your interests (i.e., artistry), that's best, as it combines the two.
[/INDENT][INDENT]Think long term; if we plan WAY ahead and are
able to formulate a sequence of events that achieves the best of both questions, we can road-map our life out. I think a lot of folks try to do this; some succeed, some don't and almost everyone ends up modifying his or her 'roadmap'. Stuff comes up, plans get altered, things happen - count on it and be ready to adjust.
[/INDENT][INDENT]Sometimes folks find that their interests are best as "sideshows" in concert with their careers/vocations. Others (like me) end up with most of their childhood aspirations sitting on a shelf somewhere; overcome by events while new interests grew and supplanted the other.
[/INDENT]I guess the bottom line for me is:
Know what you want and place that right under what you need. The extent to which you can marry the two is so much the better.
Hope this helps - thanks for asking.
