The Big Win that I once got, half of which I spent on gambling again, I should have been able to use for something unexpected "like what happened in my life few months after my big win". But, everything has happened, and I have to accept that fact. Regret, of course there is. But let it be a memory and something I can tell to remember the times when I was actively playing slots and getting maxwin. Now, this must be a valuable lesson in life, not to be careless in using money to gamble if get a maxwin.
Same as that I won big and out of my mistake lost everything along with the capital. Further the same amount stood as a big burden to me, as I need to pay regular interest for the amount I used for gambling. I've shared my story on a thread
Be a Responsible Gambler. Everything needs to be a learning, and till date I haven't completed the debt, but I do gamble in a better way than before limiting myself.
