A wife can contribute to her husband's career growth by being his sounding board. He can bounce ideas off her regarding work projects or career decisions. Additionally, she can encourage him to pursue further education or training opportunities that will enhance his skills. If possible, she could also help with the administrative tasks like proofreading his resume or cover letter when he's applying for a new job.
Another way is for the wife to be actively involved in his work - related social activities when appropriate. This can expand his network and show her support publicly.
She can start by being understanding. For example, when he has to work late or go on business trips, she doesn't complain but offers her support. Also, she can use her own network to help him make connections. Maybe she knows someone in his industry who could offer advice or a new opportunity.
She can use her own network resources to help her husband. Maybe introduce some useful business contacts or provide some valuable information related to his field.

She can offer practical help. For example, if he wants to start his own business, she could help with the bookkeeping or administrative tasks in the early days.
The husband can also be emotionally supportive. He can call or text her regularly, not to be overbearing but just to let her know he is thinking about her. For example, he could send her a sweet message saying how much he hopes she is enjoying herself.
