Not everything takes place in the open country. Thus, take personal precautions so as to live well, and don't get so awed and impressed or duped by those with power that you don't achieve enough for yourself. That's standard counsel.
Some precautions rest on individuals, farsightedness, good planning or strength in persons involved.
Some of these things can be typified, others hardly so. Let there be no grave risks involved. Be prepared for the unforeseen so that it doesn't have to happen. It should help in the long run to eliminate grave risks and hazards too. Precautions help towards that end, and sensible advice at times too.
