I gamble solo because I don't want to have doubts on what I decide because there are other players that contributes to decision. I play solo since I prefer it and I'm at peace when I have the control for every decision, it's easy, peaceful and the profit is only yours.
It doesn't matter what you choose to do but all that matters is that you win in anything that you try to do. If you have gambling friends, take advantage of them and improve your gambling results. Don't be the individual that everybody depends on for gambling results instead take advantage of the friends that you're following and improve your gambling results. If you have friends that you can't learn anything from then change friends. Do things that'll give you an advantage and help you in profiting them because you're entitled to being helped and not always the one that gives out the help. Gambling with people can be beneficial to you but you just have to know how to make use of that opportunity very well..
