It is possible, but only if you have the necessary skills. But I don't recommend you completely abandon official work. No one knows what will happen with bitcoin in the future. You risk to remain without money and pensions. You will agree with me it is very risky.
That right , you have to think of long term goals, things that would still be certain whatever may happen to bitcoin. Insurance and other health care services is a must investment that you need to have specially when you grow old and is planning to have a family.
