How's Business!

Almost daily I get asked the same question. Each and every time,I struggle to find the appropriate response. The question...."So how's business?"
There it is again.
 How do I answer that? 
Where do I begin?
Should I lie?
Are they asking me about the state of the economy?
Which business are they referring to?
I never know what to say.
Words like great,awesome,spectacular and fantastic just don't seem to capture how business really is today.
Terrible, awful,or the pits would make me wonder,"then why the hell am I doing it?"
I suppose I could say challenging or changing or in flux,but that seems kind of vague and not very energetic.
So you can see my quandary as I search for the answer to this simple question. 
If I were in the trash removal business I could say ..."picking up!"
If I were an airline pilot I could say"up in the air" or "taking off".
If I sold lighting my response could be "illuminating".
I heard a speaker who suggested the appropriate response should be "unbelievable!"
(it kind of covers all bases!)
My first challenge is that I have multiple business ventures and I never know which one I am being asked about.Or if I m really being asked about them at all.
Are people asking "are you making money?"
Are they asking "are you enjoying yourself daily when you are working?"
Do they even want to know or are they just making small talk?
Are they searching for someone who is experiencing the same challenges they may be facing and just looking for some one to commiserate with or a shoulder to cry on?
I am continually stymied by the question.
The truth is,I should probably ask for clarification when someone poses this question to me.
Which of my businesses are you asking about?
Are you really interested or are you just being polite in asking?
Are you asking about my personal experience or the state of the economy?
If I know one thing about myself is that I love business. I love doing it,participating in it,being challenged by it, being creative in it and as often as possible being successful at it .
I love the energy,the enthusiasm, the ups and downs of it.
The lulls often seem never ending.
The pitfalls and landmines are all learning experiences that prepare me for what will come sometime in the future.
That is why I struggle with the idea of retirement.Playing golf is not as appealing to me as doing business.
Coincidentally, while writing this, I received my Minute with Maxwell word of the Day.
His word was "Entrepreneur".
Being one I have come to understand that business for me is life.It is part of who I am.Yes I am a father a husband ,a friend a volunteer and a myriad of other things, but being honest , a part of me is always about business.
I suppose when asked the question "how's business?" my best answer would be..........
Nope,still don't have a clue!
