Sticktoitiveness - what is that?

My theme for the month of March is Sticktoitiveness.
I thought this was a made up word from a cartoon many years ago (who remembers Snagglepuss?) (and who will admit it?) but I googled the word and was quite shocked to find it. Here is the definition according to www.Dictionary.com

Main Entry: sticktoitiveness
Part of Speech: noun
Definition: dogged perseverance; resolute tenacity; also written sitck-to-it-ive-ness
Example: the only way she had published so many books is through stick-to-it-ive-ness.

Wow, did that ever hit home. Book writing and getting published is right in the definition of sticktoitiveness. Which is the reason I've chosen it as my theme for the month. (my next book comes out in May, only 2 months away.)

I must have a lot of sticktoitiveness. My friends and family might call it by another word (stubborn maybe?) but I really like the word sticktoitiveneness.

Of course I have written not just one, but a number of books, which you probably already knkow about me. Also as a musician, it takes countless hours to learn an instrument and master it. Not that I'm a master, I just think I've learned enough to know what parts to skip and what parts to play, and the more time passes, the more I learn, the less parts I need to skip. Hey, it's a learning curve. Life is a learning curve.

Lots of things in life require sticktoitiveness. Jobs. Hobbies. Music. Knitting. Writing. Blogging. Driving a car. Parenthood. Relationships. The list is endless, and some things require more sticktoitiveness than others. Some things are also more important than others.

So here is my question of the day. What in your life requires your personal sticktoitiveness, and why?
