Marry wisely. That does not mean marry rich, but two incomes are better than one. You should look for a partner that has the same attitude towards money as you and shares the same goals. Divorce can be very expensive.
Live below your means. If you make a lot of money but spend more than you earn you won't be better off than someone who makes an average salary.
Pick the right employer. Ask yourself annually if your position is right for you. Will you be able to expand on your skill set and move forward? Never be afraid to ask for a raise. Often women think that working hard is enough, but you have to sing your own praises.
Invest wisely and with help. It is important to seek advice from professional because they are trained specifically. You can start your search for a financial advisor at your bank.
