Sailhack, I can sympathise with your post.
I've been sailing since I was 14 (now 38) and there are plenty of times I reminisce for my days as a uni student when the long summer break provided ample opportunity for bulk windsurfing financed in the main by pullings shifts of barwork at night. They were gloriously carefree days and I was fit, tanned and happy

.
Now I'm a dad with two younguns (4 & 2) and a demanding career that leaves me wanting for more sailing time.
It ain't easy juggling those competing demands (currently in the midst of negotiating a trip up north for later in the year with the missus).
The only advice I can offer is that already posted here...you have to make the time/effort to get away, and you have to bear in mind the wants / needs of the family.
I draw some solace from the fact that a lot of the seabreeze.com.au community are my age or older. So long as I maintain my fitness I should be able to sail for another 20 or 30 years!
The blogger from Maui mentioned above certainly seems to have the life...I've been reading his blog these past few days and feeling the envy rising within. But I wonder if I would find that life fulfilling long term

.
I met a lot of older, single guys with a similar life / philosophy backpacking through India when I travelled there, and somehow they seemed a little full of themselves and their own self-importance. Not saying I wouldn't like to live in Maui for a year or two, but ultimately I think chasing wind and waves to the exclusion of all else may become a little hollow.
At the end of the day, as Hardie posted above, it's all about finding that balance. Self awareness is the key...I don't have a value hierarchy as such, but I keep a journal and I think I'm pretty well across what makes me tick. You need to invest that time to understand your own personal drivers and motivators.
