Keep smiling
Smile often and people's mood will get better.
Eat on time
When it's time to eat, even if you don't feel hungry at all, at least eat a simple piece of ham bread, which is better for your stomach and helps to stabilize your mood.
Forget "perfectionism"
Although you can't completely control your work, you can control your expectations. Put aside those perfectionist ideas and don't take yourself too seriously. What you need is reasonable arrangement and doing every step well.
carpe diem
Plan your vacation carefully and record every wonderful detail with notes and cameras.
Extrusion time
Don't always say "no time" to yourself. Actually, you can be less busy.
