I can't really startup a business that I don't really know bit about, i have to take time to study about the business strategise put creativity at work then move into it. Anything apart from the above mentioned pints, i think I should be count out of it completely
Yes, that's why I have the illustration above with a mechanical engineering student starting up a hospital. He has zero knowledge of human health and organs. So i think the best answer to give to this post is 'its not advisable at all to invest in any business you have zero knowledge of.
I really as that question because I have seen many person say the business is not really what you need to under go a training before u can start it. At the same time, I have seen such business folding under few months they were established. Running a business without much experience is a big risk.
