The reason I say this is because the amount of time you spend on making an engine will be much more than the time you spend on actually making games with that engine. And if you want to make money from your games, then that means that all those hours spent on building engines are wasted hours. You could have made some actual money instead!
I know what people might say: But my game is special and needs its own unique technology! That may be true, but there are so many other ways to achieve uniqueness without having to build an entire game engine yourself
