You say that work related stuff just isnt important to you. I would argue that it is, otherwise, you would not have gone into business for yourself and you would not have the honesty and integrity to turn down potential business. You just value your time, are not a workaholic, recognize futility when you see it (and act on it, which some of us wish we could do in our own jobs) and want to keep a balance. Absolutely nothing wrong with that.
There is a danger in many businesses/organizations right now that seem to demand blood, sweat, tears and even your soul for the privilege of working for them. You recognize it. Some of us are caught in that and have to claw our way into having any sort of balance in life (and will walk away when we can). If advancing in the world financially means giving up what makes life worth living the arts, baseball, gardening, cooking and moral living then Ill stay where I am, thank you.
The question is, what of passions that take time or that have chances of a lifetime? There are such fields. I happen to be a singer. I have more than once taken off for a few weeks to sing overseas in choral and operatic programs one in a VERY cool, completely historic place which, for me, were chances of a lifetime. It wasnt a business venture and spent my own money to go, but it was still the chance of a lifetime. At the same time, it is quite well recognized that music is one of the most selfish professions (for me its more of an avocation) on this earth. But, that doesnt mean that it comes before anything else. Id give it up in a heartbeat for family.
Its all a matter of perspective, I guess. We all have our own. Im seeking someone who understands passions like mine and who understands that staying home on a Friday night with an itchy throat and aches in some not so good places is a prudent move. (Too many performances coming up to risk it.)
At any rate, the best of luck to you.
