Leveling Up Your Skills in Stick RPG
Once you have the top CEO job, you should take your money and buy a good stock of caffeine pills. Then just do nothing but work all day and put the money into the bank. You should try to get enough for the first house upgrade.
The first apartment lets you buy a new computer, which lets you start trading stocks. This is a pretty good way for you to make some money. I'll cover that later though.
At this point, it's basically just a grind to get more skills. You'll need 666 in charm, intelligence, and strength to be a dictator and 777 in charm, intelligence, and charm to become president.
Intelligence isn't anything new. Just keep taking classes to build it up. You might want to start with this one, since getting 500 intelligence will let you unlock the car and improve your movement speeds even more.
Charm is mainly gained by drinking at the bar. Just keep drinking to build it up. You could smoke too, but that hurts your health. Remember to give money and a bottle of beer to the bum outside the bar though. You get a nice charm boost the first time you do either.
Strength can be built slowly through the gym. This is really the only option for good karma characters. Bar fights let you gain strength 3 points at a time, but they tend to be buggy in Stick RPG. Killing a person also counts for bad karma and dying in a fight means you have to reload your last save.
You will be earning money as you do this. Once you upgrade to the penthouse, you will be able to buy a television and watch television shows to more efficiently boost each skill. Once you get the proper TV, just keep watching the different shows to boost your skills faster.
Finally, as you upgrade your apartment you will be able to buy things from the furniture store. The series of encyclopedias, the mini bar, and the treadmill let you automatically gain 1 point each time you sleep. That comes in handy throughout Stick RPG, since you will gain a lot of points over time.
