Can you change a sims lifetime aspiration on sims 2?

You cant unless your sim is at university, then they have chance to change their aspiration sometime, or if you type "boolprop testingcheatsenabled true" without the quotation marks into the cheat bar, then you shift click on your sim, there is an option change aspiration, then you click on more click on that and choose the aspiration you want it to change to and then your sims aspiration changes. NOTE: your goals change after you change your aspiration so if you have been wroking on a goal recently FINISH IT FIRST!!!
