A good man/woman will increase and help you multiply the resources you have, a bad man/woman will diminish your resources. This is why choosing should be done carefully.
A partner can determine a person's steps to achieve success and this is important for men because usually a good partner will always support the work we do to achieve success. Marriage is not for a day, a week and a year, we will live a long life with a partner so choosing the right partner is very important so that they can be a motivation for us to develop. There are many people who are destroyed by their partners because they do not understand each other and there are many people who are successful based on their own partner's encouragement so before getting married we need to consider carefully.
It can't be denied, there is even a saying "behind a successful man there is a great woman" and I believe that because for a man emotional support is quite important for him to be able to build and work harder to achieve his goals, vice versa if a man without support then he tends to be more lazy without any strong motivation to achieve his goals.
I think it's all about support and indeed it is quite important in a marriage and every man has his own choice to determine which woman will be with him in marriage and every decision taken by a man then he must bear all the consequences.
