Answer:
Colby's desicion might affect other roles in his life negatively by causing a decrease of both his income and passion for his career-driven lifestyle.
Step-by-step explanation:
Initially he works for long hours, and even overtime to make good money to meet most of his financial demands. And this gave him the assurance and impression that his career-driven lifestyle was on a good track. He was focused and ambitious about his work and his efforts was met by appropriate compensations.
Deciding that being a dad would be his top priority means that he would not be able to work long hours or overtime, and this would affect negatively the amount of money he makes. And thus, might not be able to meet some financial responsibilities due to his decision.
