Right thing?

A lot of time I hear this quote 'Doing the right thing is different from doing things right'. Seriously, till now I still don't know how right is right, and what things need to be done right. Of course, its always about those other things in life that is not govern by the law. I definitely is a law-abiding citizen. There are just some things that doesn't come with a rule or law. For some people they know what they are doing, because according to them its the right thing to do. For me, its like looking for my purpose in life, always using other people's guidelines. Maybe its time I set my own guidelines and rules. Doing what I felt is right, isn't it too irresponsible? Should my rules accommodate others? By being too accommodating is it my own rules? Confusion? Things are always like cooking, too much will make the food taste funny and yet too little will make it taste bland. Then we come back to the same problem again, how much is the right amount? If I say I should have it to my own liking, but my life is not about me alone only. There are those people that brought me up and made me what I am today, should I ignore their taste buds? Quoting from the movie 'Starship Troopers', freedom is doing what you like and what you want, but not at the expense of others. Maybe its easier to follow that rule and still live life decently.
