While others have learnt their lessions of not utilizing their incomes when they had a stable source for their income flows, some others are paying adamants and ignorant to learn from what has happened to others because they feels they are not of the same calling to be affected with what happened to others.
That is a usual case, I have noticed this type of thing from several people, but what I think is the major cause of that is the inability to understand the concept that there is no difference between you and the affected person. People always see themselves different from others until what happens to others also happen to them as well. The moment you realise that there is no difference between you and others the better. What can only make you different from others
Is when you see things in another way from others and work towards it and achieve it. It's just like promising yourself that you will achieve something, and work towards it and later achieve it. Though it will take alot of time effort and consistency. Except that is achieved there is nothing different from you and other's.
It cannot be denied, there are some people who are too confident in what they know, and consider it to be the truth above anything else. There are people who when given advice hear it and then have the initiative to continue learning, and there are also people who find it difficult to accept it. That's why most people are late in many things, including investing or learning other skills that are not their passion, even though it could also increase their income.
