I just believe that we can be successful when we are conversant with some holy books verses. I could remember some verses that talk about how we can work harder to make money in the book of Proverbs. These verses are there to make us better and think more on how to be productive. In the same vein, in the book of Ecclesiastes, it talks about the more reason why we need to do more investments. It claims that we should even invest in many things because we don't know the ones that will pay us off one day.
But it saddens my heart these days seeing people always going to the religious houses to pray instead of work. They always believe that we can pray only and be rich. There are some people that always sprinkle their shop with water believe to be aiding much sales. In as much as I don't want to believe the rationale behind this, I won't totally condem it. It may be working for some people maybe because of their faith.
In conclusion, it doesn't really matter what works for us, the best thing is to try our best first and then unto Heaven for help
