If I have no target, as long as there are some winnings from my bets, I am already happy. As I have experienced many times, aiming for high gains usually end up losing most of my bankroll. So getting twice of my initial bet, is already enough if I am not aiming to go home as big winner. Sometimes you need to be contented for what you have before you wrecked your bankroll. I understand, happiness is a state of mind where every gambler has their own take on this. But you should gauge your financial situation before you plunge into debt because of your greed.
No target is wild and dangerous because we might end up playing more and we can also end up playing less. You are not a newbie in the forum and it looks like you already promoted several gambling sites in a signature campaign but I won't judge you based on that and say that you are not new in gambling anymore for you to still have no targets because some people aren't just built for gambling. It was like they are only being careful because they heard how lethal gambling can be if the urge won't get prevented.
Anyways, the ' some winnings ' that you mean there must still be a nice amount of money because I'm sure that no one gets contented and happy in a tiny amount of profit, and in order to achieve a win like yours, you must also be betting a slight high amount of money. If I'm in your shoe, I will not think twice anymore but I will also secure most of my profits.
If you notice, I didn't said that I will stop immediately because there are still be residual amounts yet in my balance right after the win and I can use this to test my luck further. I already experienced that sometimes the result is still great, so I can evenly grow my balances. If not, I will now stop and withdraw all my balances.
