I don't wanna get all dark and depressive on you, neon....

...but, since you asked...
Just kidding.

I used to have dreams, much along the same lines as yours, but sometimes dreams are just that.
I have pretty much realised most of my dreams and hopes - I got married, owned a house, have two gorgeous kids, and reached the top of my career ladder.
But for me, I guess it all happened too quickly.
I'm getting divorced, the house is sold, and my job is something that is required rather than enjoyed.

But I do still have two gorgeous kids, for which I am eternally grateful

I would advise you to live your life as a free-spirit for as long as you are able.
Become a biologist, as you want to be - it is an admirable career to persue - and doing something that you enjoy, is as rewarding as any pay-check that it will command.

My personal future is uncertain, as I am 'between places' right now, and kinda live my life from day-to-day. It's cool, though, I have my kids' future to worry about, and want them to have the best possible outlook that I can provide them. I concern myself with giving them the tools to approach life with a good grounding in manners and respect, and try my best to keep their minds open.
I want them to be shepards, rather than sheep.

I believe in Fate, and so I await the next door
