Sorry 777! very difficult task ..you are setting for yourself... its impossible... to make everyone happy is not as easy as it seems... Yes what you can do..be harmless for others... don't hurt them...treat every one with respect & love ..... regardless of age, gender, religion & status...be kind & polite...help them in whatever capacity you are dealing with them...but do remember.. people are so good to take you for granted... they will start taking advantages.... Set your priorities & principles also. Wish you happiness!
You can give them everything you have, all your money, everything, then you can do for them whatever they want. Don't bother thinking about yourself or your own happiness because theirs comes before yours. Oh and by the way when you are broke cold hungry and naked, they will still come for more because they always think you have more to give. That won't make them happy because they think they deserve it and your withholding or hiding it from them.
my grandfather always told me you can never please anyone without pleasing yourself first. make sure you are happy then make others happy. you can't please everyone though. that's where it gets hard. i always tried to please everyone and ended up losing a few friends over it.
