if you use your energy to train a stat, after you click the Train button, another message will appear above these:
Amount of Energy :
Statistic to Train :
Personal Trainer :

saying "You begin training in self-defense techniques.
You have gained ......(a number) Resistance development points by training it 5 time(s).


if you don't have a high endurance and happiness, the gains will be very little and you will have to train very much to see a difference. Also, go to preferences page and change the stats display to number if you have the green bar. you will then see the change better..

Donator status helps at getting more development points.

Happiness can be improved by buying a more expensive house, and endurance by taking the classes and buying it with credits...
