I would advise you to study Python first and look towards data analysis. There will be even more developers of any client software in 5-6 years than now, and the profession will most likely begin to depreciate slowly. This has already happened in our century with lawyers and economists - some of my peers were burnt on this. But data mining and machine learning are a trend for at least 10 years, and there it is highly desirable to have a specialized higher education, and in principle you need to know a lot and think well - the sooner you start "sharpening" yourself, the more success you will achieve. You can learn to program applications in parallel, without fanaticism.
Familiarity with C ++ never hurts. You won't get away from it in game development or high-performance systems. But I would not recommend starting with it, there are many nuances that are difficult for a beginner.
I'm 14 years old. Is this a good time to start learning the language? Know Pascal?
Yes, quite a good time to start.
But I would start with a more modern language. I advise C # (C Sharp) and don't give a damn about Pascal no matter what Pascal is taught at school. Pascal is an inconvenient and outdated language with a poor development environment.
Look at my answers, I have already described how best to start programming in Sharp.
Good luck in your endeavors.
