My personal text: ...gambling responsibly. Do not be addicted. If it is in full, it is 'I am gambling responsibly. Do not be addicted'.
This should help people that see are gambling to know that gambling responsibly isnthe best way to gamble. If you use 5% of your monthly income to gamble, not going beyond responsible gambling budget and having discipline. You are in the right way.
If you can not do that, do not gamble at all.
