Gambling is not the only thing that makes people addicted, those people who crossed you may also one day become addicted to alcohol and drugs and ask you for help. In a world like the current one we cannot afford to fight with other people and distance ourselves from them because one day we may need help too.
Just look at articles that talk about people who were rich and became poor.
That's the thing, people didn't cross me, but I let them down by not being able to return the money I borrowed from them on time. They lost trust in me, and that's the most important thing in our lives. That's what happened. I still can't forgive myself for it. I let down people who were counting on me. Yes, mistakes like these change the entire course of life. Now there are no opportunities like there were before.
Yes, there are a lot of dependencies in this life. Even tea causes a strong habit of drinking it daily and several times a day.
