What is "comfortable"? I know they have their metric.
If you aren't in any debt other than a house/car.
Are socking away money for retirement.
And have enough left over for you and your kids to go do fun things.
You are living more comfortably than almost anyone on Earth.
It seems like comfortable has become going to Hawaii every 6 months, multiple vacations a year, 2 brand new vehicles, etc. etc.
