I voted “8” and I am pretty content and happy right now.
Pros:
Great job - I get to work from home, travel for work about 1-2 times a month, and I make (IMHO) a pretty darn good salary. I’m valued and respected by my peers and senior/exec management. My manager is very hands-off with me and trusts that I’m doing my job every day and does not micro-manage me. I honestly love what I do right now.
Home - I own a house that I love and am getting many of the large projects/improvements completed.
Friends - I have a great core group of friends, some I’ve known for 25+ years.
Finances - I’ve not been in the paycheck-to-paycheck grind for quite awhile and my current income affords me the extra income to indulge my Want Monkey. Being single with no kids helps too! Haha
Relationship - Dating a great woman for about a year now. She is affectionate, loving, funny, and brilliant. It helps that she is also tall, blonde, and has great ta-ta’s. 
Cons (or the things that worry me):
Home - My place was built in 1890 and boy can it be a money pit. Additionally, due to the house market getting crushed and already owning in a neighborhood that was building momentum and gentrifying but has lost a lot of the gentrification momentum and property values have tanked, I’m now underwater and owe more than the house is worth. Although I had no plans to sell anytime soon, I know I won’t live here forever. It worries me that should an opportunity arise, I’m kind of stuck with this house unless I want to take a substantial (to me) loss.
Finances - I just don’t know how to save and invest for retirement properly. I’m woefully unprepared for retirement. I’ve recently significantly bumped up my 401K contribution amount but that is probably too little/too late. I know I need to significantly curb the discretionary spending and redirect that income into retirement/investment funds. I’m the literally “grasshopper” in the childs story! Hahasobhaha!
Self-Image - This is the single biggest thing that causes me to be unhappy right now. Definitely not my single biggest issue (see finances above) but the one that hits me in the face every day. I’ve put on to much weight the last year or so and I’m very unhappy with my weight. (5’9", 215lbs) I was just looking at pics from St. Patrick’s Day and I was really embarrassed to see how big I’ve really become. I guess my image in my head of myself was that perhaps I’m carrying a few extra pounds but I’m still a pretty fit guy… Crash-Boom-Pow collision with reality right there!
Relationship: I’m 40 and no kids. My girlfriend is fantastic and I can see this has the potential for long term, i.e. marriage. The biggest problem is she does not want kids - ever. Now, I can’t exactly say I can see myself as a father right now. I enjoy my life as it is and the freedom I have to do all the things I do. On the other hand, I am feeling a bit of that “Oh crap dude… you are 40!” and I have had moments of envy when seeing some of my friends start a family. I guess how I feel right now is… although I’m not pushing to have a kid right now, I can’t honestly say I’m ready to take it off the table. This gives me pause about my current relationship. 
So… A few changes here and there, some minor and some fairly significant, and I’d probably peg myself as a 10.
