To sleep or not to sleep?

on a ferry, sleep!

but how to know if sleeping or training is the best?

this morning i should have slept! i was to tired to train, it took me 15min skipping and 30min with mr.long before i figured out i diddent get anything out of only doing mistakes. and went for shower and a breakfast.

but how to know if its a normal morning-tiredness that will disapear after 5 minutes warmup?
or if it is a tiredness because the body really needs a rest?

now im going to bed, so i can get ready for the afternoon training.

zzzzzzzz
