To get to places like the park, click the place so you're there, and use the whistle to call your sims there. same thing fr the sports centre and houses, yah.
to get money.. And efficient way is gardening. Almost every night I make my sims plant green beans, which cost 111 or something like that to plant, and while I'm sleeping overnight they get it done. There are no drastic changes of mood like sleep, hunger or potty for that matter..
If you don't prefer gardening, get a job from the workplace or business you just get. The sports centre can wait- only preteen sims can pick up the hobbies, and there's really no use for it if you haven't excelled that far in the game. and for the soccer ball, I do not know.
