I'd go first - Stay out of debt as much as you can.
Another big and major advice is that you should not act like you have when you do not have, that is, don't act rich when you are broke. You should not be ashamed to say you cannot afford something out of embarrassment. Another major reason why you should not act rich when you are broke, is so that people that intend to help you, will not look at you like you do not need help because of your act, when you truly do. I have met persons that their situation needs helping, but they are still too proud or not true enough to themselves to act sincerely, instead they keep telling lies and acting okay, truth is, nobody will force help on you, before someone can help you, you have to help yourself by accepting that you need help.
I don't know what you mean by "help," but I don't agree with you one hundred percent. If you read or watch the stories of people who have achieved success, then they never allow themselves the thought that they have no money, or they should make people feel pity. A person must achieve everything himself and not depend on someone else; this is the first rule of successful people. Acting like a rich person is not about spending your money right and left. Rich people always know how to manage their money, and just thinking that I deserve it and have it or will have it has always worked positively.
