If luck permits and you manage to deal with taking small profits and stop your session that practice gives you decent chance not just to enjoy but also gain something as bonus to your day.
And also it will not ruin your day when you take profits even if they're small. That should be the goal of most gamblers, to profit. Because others even when they're in profit, they don't stop at all. They continue to gamble and don't settle the profits that they should have. But instead, they are not removing the portion from that profit the capital or bankroll that they have started with. It ends badly and even the bankroll that they have started with, they're all losing and that's why it's a bad decision from a gambler when they are ignoring the fact that they have profited already.
