You'll be spending a lot of time in front of your computer, so you may want to invest in a comfortable chair. It'll be worth it, though; only 10% of computer and information system managers earn less than $74,000 per year, and the top 10% earn over $180,000 per year (source). The hours are long and there's the potential for overtime, but at least you'll never be bored. (Or poor. Or poor and bored.) 

Computer science majors have a lot of career options to choose from: information technology (IT) architect ($123,000 per year median pay), data scientist ($114,000 per year median pay), or management consultant ($105,000 per year median pay) (source). And most of these careers require only a Bachelor's degree in the subject, so you'll be making fat stacks in no time.
