>>You are an independent developer, right? There are many who are more at the mercy of the market whether they want to be or not. I would love to stay with Foxpro for the rest of my development career - I'm very comfortable coding in it - but I have found it harder and harder in the past 5 years to find contracts/permanent positions. I think that there are two sides to this. If you have the choice to only learn/use one tool great, but when you don't have the choice, what is wrong with having mulitple languages in your toobox?

Others also said that it depends on what the nature of your work is. Depends on who you want to quote.

You didn't actually address directly anything that I wrote. I would like to know what you feel about "If you have the choice to only learn/use one tool great, but when you don't have the choice, what is wrong with having mulitple languages in your toobox?"
