aaaahhaha!
You have it!
You admitted it finally!
I was wondering when you'd finally fold...
I remem. long time gone... you were saying "I'd never make this my life"
hahaha...
you got the disease bad my friend.
the ailment has weaseled it's lovely way into your soul.
Good for you..
don't fight it...
It feeds the soul...
and can help feed the wallet if you aim smart.

And yeah...good thing...stay outta tattooing ...even designing for tattooing...
A- it's cutthroat market saturation.
B- until you get a name in that industry ...the pay is not grand...nor is it easy to get known...the best are cultural and geo/chrono period masters...and those are the artists. And that is alot of study...alot of work.
C- I know ..hehe..colourful past of mine...when I was a kid I used to airbrush harley gas tanks and do some tatt work for a bike club...
whooo those were the days...crazy crazy crazy days.

yeah man...stay outta tatt work ... can be a slippery slope of fabulous fun there..the partying, the girls, the...well you get the idea

keep you nose clean.
