There's how long it takes, and there's how long it feels like it takes. For me, the lack of mental stimulation while doing tedious work is the biggest issue. While I am a slow painter and somewhat inept, I can paint new construction when it still has subfloors. I have found that painting with someone else is great (one cuts in while the other rolls the main surfaces) since it gives me someone to chat with. If another person isn't available, music is good, but I prefer recorded books since it occupies the part of my brain that would get bored without something going on while the purely visual part of my mind is occupied cutting straight edges and checking for full coverage.
One of the most important factors that determine the success of a small business is the right choice of line of business from personality fit standpoint, . the extent to which it corresponds with your entrepreneur type. We distinguish 9 entrepreneur types , such as business leader, freelancer, analyst etc. If the nature of the business and your entrepreneur type do not match up, you run the risk of losing your business, together with the money and effort invested, never mind the frustration and loss of self-confidence.
