Date men from United States / California / Hollydale, 33 year old

Date a man from Hollydale, United States. I'm kinda workaholic, I work 12 hours a day, but its because I want to payoff my student debt and save up for international travel. I also go to school at Cal State Long Beach. I'm going for my second master's degree. I have an MBA and the pursuing a MSEE. My life is pretty busy, added I have a 7 year old son who keeps me on my toes.
I am an easy going guy that likes to go out and have fun. I have to admit, I am shy, but if I get to know you I have no problem talking up a storm. I will also say I am a quite person, I think it makes for a better listener. Conversation is a must, and its fun when we can have a good time. I am always up to go for a cup of coffee or maybe drinks, depending on the mood. I like to know things and see what people see. I guess you can say I'm a people watcher. I like to know what people are thinking.
Traveling is one of my great escapes. I've been to New York several time, Canada, Texas, Seattle, and different parts of Mexico. I have also been to Panama, Rio de Janeiro, and Bangkok Thailand. Looking forward too many more trips. Looking to seeing all of South America, Asian, and one day Europe.
What am I looking for.... not sure. I would like to meet a new friend. I am not expecting to meet the love of my life or find my new best friend. But getting to meet someone to have a good conversation and share a drink or two. Working and education take alot of my time. I never get to stay after class and talk with classmates because I have to rush off to work or have another class.
I'm a realist. I don't believe in a half empty, half full glass. I just the the glass is there and it has water. I like listening to people, its fun to to hear what people say. I don't think people really listen anymore. We're all too busy trying to say the right thing. I rather know what you think is true. I think its hard enough to be just a friend let alone a relationship.
Tell me what you are looking for in a friend or in a relationship. What do you think is the hardest part of keeping a relationship together?
