Can't finish outdoor enthusiast aspiration with Never Weary trait

This frustrates me to no end at times. Sometimes I get a ding ... sometimes I don't. Then you have to wait a full day (or two) to try again. If you are in an active career and get pulled to work you also won't get credit for sleeping in a tent. I couldn't get sleeping in a tent to work for vampires at all.. I did finally just give up.
The one thing I use to do... was have a sim with the piper trait make another sim sleepy with music. For some reason that worked really well for me... but I had to have two sims and one with a completed musical aspiration to achieve it. You can use other powers and potions though I'm sure to decrease your sims energy enough so that they will sleep through the night. I felt all smart and stuff doing it then but it's not really a great option to depend on.
