how many HOURS a day do you meditate?

[Parsons]

You know... I am STILL trying to figure out meditation. I know how important it is to my path, but nothing seems to "stick". I will go and sit on my bed and try to meditate for 15 mins - hour when I renew my efforts, but nothing of substance seems to come. It just feels like I chose to sit on my bed and do nothing for a half an hour. I have been able to think of "nothing" for minutes on end until a car drives down my street or I hear the dog stirring downstairs. I have also tried focusing on specific things, but this is more difficult than thinking of nothing for me since I start automatically extrapolating likely future scenarios around whatever I tried to focus on.

This matter is of the utmost importance to me, yet I can't seem to figure it out. This is the same problem I have with starting ANYTHING new: I just don't know where to start.
