The joy of discovery and the time it occupies is an investment. I have been in this business, an though I produce a lot of functioning site, my own site is never finished, never fully designed, never fully optimized, never fully functional, because I am always doing something to improve upon.
Your site will be design, redesigned and so on, sometimes for the better and sometimes for the worse. However, remember what you do for a living and don’t let it consume your time when a simple page, template and design can sell your work very quickly.
Then enjoy what Roberto referenced to expand your abilities and fine tune your site as you grow.
I hope I don’t sound patronizing, but I have been where you are at many times in my career.
I wish you luck and… have fun.
BTW, I think EditorX is such a unique tool that has opened so many avenues for to me to produce sites for my clients. If I am wasting my time at Wix, I am sure learning a lot.
Cheers! Good luck!
