Learn Hebrew - Half Way There

I didn't get a new word today and I'm worried about how much do I remember now? Yet, I've somehow managed to get to day 15 with not much trouble. That's pretty sweet. I recited the 3 new words yesterday, but now only remember 2. So here it goes:

1. shavu'a means week
2. shanah means year
3. luach shana means calendar
4. hayom means today
5. etmol means yesterday
6. machar means tomorrow
7. sn'niyah means second
8. dakah means minute
9. sha'ah means hour
10. sha'on means clock....this is the one I forgot last time
11. besha'a means o'clock
12. yachol means can
13. hish'tamesh means use
14. and I forgot this one. The one I forgot to remember is asah which means do. the most simplest word

My new word for day 15 is halach which means go. Achshav (now) let's see if I will remember machar.

The hard part of this challenge is not dropping it and moving on to the next one. I already have so many new ideas/
