Investment is a choice though, depending on the personal choice. The steady income would lead to the possibility of investments and the lack of which will not. Hence steady income is important.
Some people will never come to the decision to invest because they cannot come out of analysis phase. Some will stop investing because of prior losses without looking at the quality of assets.
A little bit of homework here might lead to better Investment choices.
Our elders have said that if we don't lose something, we won't gain anything. Therefore, if we think that we can improve our situation and our work by making some investment we should not be afraid, but we should do this work with faith in ourselves and work hard which will never decrease us and our work. They understand that if we invest money, we will lose, so how will we recover whereas in business loss is clear and has to be expected. I would call such people fools who are afraid of becoming their own standard and also reduce their progress.
