I can remember back to my first "professional" job circa '71 (that's NINETEEN 71, wise guy
). Had withdrawn from college, no work, nothin to do, no money, no dope, no hopes. Landlord and grocers wanted money.
Friend had a friend who could use help painting.
Anyway, that was the stage.
We were painting the third floor "rec" room (pronounced "wrecked room"). Real painters in the living areas. One of them made a comment about a kid they once hired who took about 45 minutes to cut in a ceiling line about 12 feet long. I ALMOST said, "what's the matter with that".
Well, it mighta taken me a dog's age to cut a line, but it was good. My level of acceptance was much higher than my skill.
With practice and a desire for perfection, I got quicker and even better.
If you have a high regard for quality, you will know what is acceptable. As another sig line I use says, "Strive for perfection, settle for excellence"
I have seen lines that don't belong in a dog house, I have seen lines that Michael J. Fox and Muhammad Ali blindfolded could cut better. Inexcusable.
Just keep at it until you're happy. Build your reputation on YOUR ability, not ours.
