Leaving after an hour when I've won - leaving money behind?

[JackAll]

A normal session for me is often win moneys, lose small bits like folding to raised c-bet a few times, win more good sized pots then when up 300-500 I stop. This is often within 1-2 hours for most days and I only play about 10-15 hours a week (save for bad beat days once or twice a week where I play for 5 hours or so getting back to even or so).

Sometimes I wonder if I'm missing out on a lot of money by stopping when i am up 300 or so. 6 days of that is a good god damn salary to me, but I wonder if it could be way more

I always think stopping before the bad beats leaves for a nice day afterwards and I hate the stress like a mofo.
But I dunno ... might be missing out on lots of $$$
