I tell people you don't have to be rich before you become independent, there are some things you will never see or get as long as you're still under your parents roof eating their food and hiding under their wings for protection.
As a guy around the age of 25 upwards should have learnt how to survive on his own, even if you're from a wealthy family, you should know your fathers money can never be like your own. You've stayed with them from your childhood, you've gotten the training you need, its time for you to move on, thatsbwhy I don't encourage parents sending their children to boarding schools. They need to spend their early stage of life with their parents so as to learn the necessary things of life, mentor them, coach them into becoming great because they are not meant to spend all their time in life with their parents. Before they grow up to the stage of getting to the university, they are well equipped with the lessons you taught them. Train up a child in the way he should grow and when he is old he will not depart from it.
The reason you're leaving your parents house is not so you can be unaccountable, living life to the fullest, lavishly spending money and jumping from one woman to the other. No, the essence of the freedom is to exercise the ability to do what is right, the opportunity to enlarge your self and make your family proud. You might leave because its time to pursue in that dream of yours they don't believe in and they are trying to bring you down. Leave and achieve your goal not leave and waste your life.
Our parents always wants to be there, always want to protect us because no matter how old you are, to them you're still their little child. They love us so much if we are not careful, we may not be able to break out of that love and at the end you find yourself not able to do anything.
