First stocks! Chose GXY..

Hello all, I figured this seemed like the perfect place to come to.
In November I took the plunge and bought my first ever (!!) stocks... and I chose to do so in GXY.
I bought in at 11c, so needless to say I am very pleased.
I only bought a little amount, so also kicking myself.

I chose Lithium because a) i'm an avid supporter of smaller companies and wanted a growth share rather than one with dividends, b) lithium is needed and will be hugely needed more and more so in the future, so it was a no-brainer in that regard, and c) production hadn't started so I knew the price would grow.

But that was the entirety of my thought process... so no need for harsh words, as I said - I am a FIRST time entrant into the world of stocks and shares.

I guess I am after a simple breakdown on everyone's thoughts on how well GXY prices will go? And why.. I really want to know the why.
Where do you see the future.. and why?
If you were to sell... why would you do so, and what would be the first indication to start this thinking?
If you were to buy more... (as above).. ?

Help a gal out!

Thanks
