Not exactly in engineering, but studied computer science and currently am working in IT industry.
I can at least speak for my study: It can be difficult, but it won't feel as much if you're actually into it. People's brain are built different from one another, so in the end it's case by case and won't apply to all.
What makes you consider engineering? I don't mean to sound too discouraging, but if it's easy money you're looking for, you won't find it here.
