How to manage working 7 days a week?

I’ve just started an internship in animal research with the intention of doing my postgrad in the same field. The job requires me to be on the field feeding, refilling water, cleaning, collecting data, and other general research stuff for about 50 chickens. This means I’m working 7 days a week, on the field doing all that stuff twice a day, for the next 6 months, and that’s just the field work. Data analysis and report writing is gonna come right after that. I’ve been on the job for about a week now and it’s just so much more tiring than it sounds. It’s really hot out this time of the year, and the facilities here aren’t all that great.

I can’t really miss a day because if I don’t feed the birds, no one will. I’m really dreading the work that’s to come and it’s making me think that maybe I’m just lazy.

Does anyone have any advice on how I can cope? Time management hacks? Words of encouragement? I’d appreciate anything really.

Thanks in advance xx
