Change Clothes
The first cheat to increase GPM is to change the character's clothes a lot. By changing his clothes, you can earn 16 GPM points on Confidence. Continual changing of clothes can get you about 5 GPM points. Make sure to change him into clothes that have high sex appeal, because it will increase the amount of GPM points you obtain.
Drink Coffee
Another easy and quick way that you can raise the GPM is to have the character drink coffee. A Latte is the best choice because it adds +10 to the character's confidence. It can also quicken his pace at work. An Expresso is another good option.
Bar
Another fun way to increase the GPM is to have the character go to the bar around 2:30 p.m. Chose to drink a Martini because it will increase the character's confidence tremendously. There will be a drunk meter. Try to avoid getting the character drunk or his confidence will plummet.
Work
At work, you may earn up to 9 GPM points as well. You can earn these points by researching and answer Margot's questions correctly. If you answer a question wrong, Margot may forgive you depending on where your performance meter is at.
Flirt
Flirting with Hugh can increase your GPM as well. You can flirt with Hugh by talking about fun, sharing work information or even giving gifts. Do not flirt with Hugh when Margot is near you, otherwise you will lose GPM.
Take a Course
Taking a course for work will earn you extra points. You won't be able to take a course until you earn enough money from work. The courses you can take range from writing to fashion design.
Be a Bitch/Insult
Being a bitch to Hugh and sometimes even Margot can also score you points. It is not always appropriate to be a bitch or insult your co-workers.
