Never get comfortable with the amount of customers you have. Word of mouth slowed down and I have lost a total of around 4-5 customers this year out of around 30. Two died, one that I saw a day before helping fix a bird feeder she passed away like 10 hrs later. The others I lost due to high risk because I have a 26 inch titanium rod which I had installed since NOV 2, 2013. I am 30 now and thank god so far I can work without pain 99% of the time. I did a walk in flower bed with 1.5 yards of riverjack rocks. Keep moving forward! That's my tip never stay neutral but at the same time be able to handle the amount of customers that you have. I did gain 3 new ones though, one being a woman that new my friend and I from the motorcycle accident. lol just one customer from my first time using craigslist.
