I'm exhausted

I've just taken on a project which is requiring a lot of muscle work and right now I feel like a sack of potatoes. I might be working on this for about 2 weeks which means I'll have no time to meditate. I guess this is a great opportunity to try to be mindful (meditate) whilst working on my project.

I have a feeling that from this exhaustion I might have an astral projection. Here's what happened the last time I was this exhausted.
