conversation: User (Lur42): "I know that it would make sense that it is based off of income, but, is there a max number of cc's one should have?   Also, I know that total utilization should be less than 10%, but, what should the total limit be compared to income?"
  Self: "I would say 3:\n \nVisa for daily purchases and travel points. \n\nMC for safe internet spending. \n\nAMEX for big purchases. Given your credit is good.\n"
  User (Lur42): "Is there some sort of magic ratio though?"
  Self: "Are you looking for spending/income ratio? That all depends how you manage your finances. There is no golden ratio IMO. Pay your bills on time, save, don't overspend on CCs since debt servicing is over 20%."
  User (Lur42): "Yes, a spending/income ratio I suppose if there is no golden ratio just a range would do.  Forgive my ignorance, but, what is debt servicing? "
  Self: "Interest rates e.g. if you borrow money, it costs you to borrow money. However if you pay your entire visa bill right away then you do not accumulate any interest - it is very good for credit building"
  User (Lur42): "TIL thank you :D"
