must feel motivated after work

Not sure if i'm lacking motivation or i am simply tired from everyday work and weekly Jap class. Everyday after work, I just refuse to do anything except being a couch potato. Phyically I get tired easily too, not sure if i'm low in adrenal or my body refuse to work hard(except office hour).

Last Sunday, I set my mind to do a pair of earrings but I keep making mistakes from the making, and ended up spending few hours just do 1 side of the earring and is still not perfect.
The next day, I try again and with the good mood and good inspiration, i managed to finish 2 pairs of earrings in one night after work.

Viola! I am trying hard to keep the flame. Do let's the motivation coming.
