It really depends on your priorities. As I recently read, there are two things we budget - time and money. However, while we (can) have a decent handle on how much money we have, we don't have any idea how much time we have. As the saying goes, none of us is guaranteed tomorrow. That's why it's important to maintain balance in your life. It's ok to prioritize earnings for a while, but don't stick with it to the extent that it becomes your sole motivation in life. If you do, sooner than you expect, your sacrifices of family, home life, friends, hobbies, partners, etc. could become permanent.
