My sim can't earn fame points

Guys, even though the rep bar don't have a bigger counterpart if you want to know more precisely where you are at click the fame button and it will magnify the fame bar, Dark Green Fame, is how munch fame you have that won't deteriate for a while, the lighter green and yellow represents the fame that can decay first. I do not know if the Dark Green one is locked fame that don't decay. Also another thing I noticed is if you have a sim that your job requires a lot of skills unlock the noticeable fame perk, this will add the green +fame option to both your careers daily tasks and the skills people have taken noticed in. Also remember famous people must show the talent in the public for it to count.
