OK, time to start my list of pet peeves.

When you write code that results in a hint or warning, don't treat it as a congratulations message that everything is going well. Instead, take the time out
NOW to stop and fix the hint or warning. If you start getting sloppy and letting hints and warnings go, then you will inevitably get burned later on as a result of this.
One perfect example of this was a project that had hundreds of hints and warnings accumulate over the years. One day, a hard to reproduce access violation got reported. Since we didn't have a test case, we had to walk through the code by hand. Finally, I noticed that a variable could possibly not be assigned in one code path. I then actually said out loud "That's funny. I would have thought a warning would have been generated." In response, the developer said "Could be. I don't know. I turned off hints and warnings because there were so many of them." We turned them back on, and sure enough, there was the warning that I expected. We fixed the code, the warning went away, and so did the AV. Shortly afterwards, we took the time to clean up all of the hints and warnings. Heaven knows how many more potential bugs we avoided by cleaning those up.
Hopefully, you can learn from this mistake by just reading this. It's a lot less painful than the alternative.
