Investment is the process of putting money into a structure you have used knowledge and information to analyse. It's the ability to bring back returns to you in multiple folds.
Just like in planting you must plant your seed/capital and it must die/change its form before you can expect a harvest/returns.
You must have a good knowledge of the kind of investment seed you want to plant.
You must be able to determine the kind of investment you are doing. This is where investment in knowledge and intelligence comes in.
You must realize that there is nothing like: l don't have, because you were created with a brain.Nobody came into the world with clothes. Those born into rich families have to leave empty at the end.Some even live very poorly.
Between when you came into the world and when you are going to leave, it's time. And this is the time you are giving to act on the ingredient or your brain. Wealth is hidden in your ability to sustain it by multiplying it.You need to relax and find out how you can put all the things God has made available into a profitable investment.
You must also sustain what you have produced by multiplying your income. The liability is not how you receive your income but how you are able to use it,reproduce it or even multiply it in assets for your children's children. This is the only way to move from,"I don't have to living in excess".The road to wealth has poverty as resistance and only risk-takers can fly over the obstacles.

There are several biz out there, but you must analyze your own interest.Also endeavour to observe your community and know what commodity you can sell there. Just have it at the back of your mind that to really make money you have to sell something.
