I've had several concepts of who I was to be. For a long time I considered it to be an Engineer, to the extent that I took five years of school to receive a degree in the field. However, after that ended, with some advice from my father, I found my true love to be in antiquity, and as such have set my heart and goals on being a Classicist. As such, I am just now beginning my Graduate work in the field (in particular ancient Languages/Literature, with a specialty in Aeschylean tragedy... I'll be one of the few in the world who has a focus on the Seven Against Thebes), and hope to continue to do so until the day that I can teach as a professor of Classics (which, I must add, most everyone that has met me can see me being quite naturally.)
As opposed to what you say, Knight, I have never thought of myself as someone blowing freely in the wind as to my future. Even though it has changed, it has always remained certain, and they were not things that came about unexpectedly but out of my choice and careful consideration. I cannot recall a time when I felt that my future was some airy unknown. I might not know where I'll end up in a few years (where I'll take my PhD, where I will teach, and so on), but those are the specifics. The generality of who I will be (provided I've not died... as a would-be Stoic I simply must take that possibility into account so that, if it were to happen, I shan't lament it as unforeseen!) is certain to a large extent.
I must admit, however, that many people remind me of how much money I could make as an Engineer. And this is far more poignant where I live, as I live in Alberta, right in the middle of the affulent oil sands, and at the moment the need for engineers is extremely high. Even the tradesman make a great deal of money, and if engineers are well payed typically, here and now it is far exceeding what is normal. So I'm always looked at rather strangely that I choose to forego that wealth (as for a bachelour of my years and state to work for 100 grand a year would indeed be wealth) and choose rather to indenture myself for the sake of school. But when one has a purpose and calling, it matters little what the monetary benefit is... no, the thing itself is the reward. That, ZeaLitY, is the Springtime you speak of so highly.
That said, Knight, I would wish to veer you from Archaeology to Literature... but make not mistake, I have a high regard for the archaeological community as well. The variant facets of ancient studies are intrinsically connected, and it is one of the grave errors of the past to treat each in such isolation as was done.
If I may ask, however, what is your ideal focus in archaeology? What era and region?
