RE: screw all the technicalities!!!!!!!!!!!
David and Jeff and others who have spoken about balance and consideration have it right I believe.While putting in the time gets it done,the wise use of the time you have get's it done also.Choosing to concentrate your efforts when the most elements are to your advantage increases your odds.
Everybody's circumstances are different but I know a lot of guy's who have lost their spouses and families because of the time they have taken away from them.
