I find that diversifying is helpful. I started with a screen printing shop that I purchased from a former employer. I already had job experience at vinyl cutting shops prior to working at that shop, so when I took over ownership of the screen printing shop, I got a computer, software & vinyl cutter to branch out from screen printing. That kept my interest when I was starting to get tired of the same old same old squeegee pulling, screen cleaning, monotony... and then later i decided to get an edge printer which gave me more variety. At that time I also got more into using photoshop & designing differently to make use of the diverse Edge printing capabilities that were not as easy or not possible in cut vinyl... and that new design direction also helped keep the growing diversity of self employment from getting stale...
Back then i got to where I couldn't even consider a vacation & one year I had my daughter's H.S. graduation & my brothers wedding the same summer & both trips were like long weekends with almost more time spent traveling then relaxing...
...so then I started studying business books & began working with Jon Aston a bit as well.. plotting a course for me to grow my business to the point of being an employer who did not have to do everything himself. The theory was that I would at least be able to take a vacation some day & not have to close the business down & rush home before I even got to relax. That was years ago, but it was an important goal for me & I put a lot of energy into it.
Over time i did make that transition, and once I had qualified help, I felt more comfortable with more equipment purchases too, because i was able to turn more manpower into more profitability, & I had someone to crank out the bread & butter jobs, while i learned to set-up, maintain & profitably operate the Mimaki inkjet printer I bought... so again, this growing & changing kept my interest & excitement for this industry high, & kept my willingness to devote 60+ hours a week to building a viable business... & of course large format & photo quality capabilities also enhanced my design skills, which i made a concentrated effort to increase in the areas that would capitalize on those new equipment based design opportunities...
The other opportunities afforded by having employees was that I did finally feel like i could afford vacations & among other things i started going to a few Letterhead meets, sign conventions & sign workshops..
Basically thses sort of intentional growth phases have always led to renewed appreciation for the things i love about self employment in general & this industry in particular.
Folks who ave read my posts over the years know I have also began to focus more on building a website (with Joe Diaz), learning other marketing skills, and of course another recent equipment purchase of a CNC router.. so I have plenty of new opportunities for learning in front of me, still work over 60 hours a week... and still love it as much as the first sign job I took in 1989 when i knew instantly that I had found my life's calling
