The most important tip is to know who you should form your group with. The most important criteria to consider while forming a club with friends or colleagues is to know if you really “trust” him/her with your money.
You group should only consist of friends, family or colleagues that you can really trust with a certain amount of money. For eg, I can trust someone with Rs 5000 but then I will have my doubts with lending him Rs 15000. I know his or her attitude towards money, I know his family, where he lives and most probably know what he would do with the money.
With this group you should not have any inhibitions in calling them up to contribute on time. At the same time you should be able to go out of your way to help them when they’re in need.
