The ultimate question

This blog may go no further than a simple question. I require feedback.
Do I have to choose between love and a relationship and school?
Here is the background information you need to know to answer properly this stupid question.
I am a difficult person to live with and be with, I'd say at times, but realistically, most of the time I am difficult. I am moody, and excitable, and sometimes loud. I am creative, and I don't sleep a lot, and I tend to come and go as I please. Having said that, the coming and going is mostly because there is no one to keep me in bed.
I am a creative person, and sometimes this means questionable behaviour. I make no appologies, and I like to experiment with various organic substances. I have weird thought patterns, and do not understand people.
I may never have children of my own. I want children someday. I want to adopt. Thus, in my 29 years of wisdom, I am not averse, or opposed to the idea of raising someone else's children or child as my own. I know even saying that is out there, but I do believe that children should have love and support. I have that to give, even in a 'non-traditional' situation. I have a huge heart.
Sometimes, I require protection from myself. My good friends know this. I have close friendships that mirror relationships without sex. They mean a lot to me, and I will always have them. This does not mean that I am incapable of having a relationship with someone else. Those people are protective of me, and they will always be wary of new 'men' in my life.

Enough about me personally.

Academically, I am smart, I know I am good enough to do grad school and get a PhD. I am transient by nature, and like to travel. I do not put down roots, and I get very wrapped up in learning and studying. So wrapped up that the entire rest of the world does not matter at times.

So given all that; Is it possible to have both? Do I have to choose?
