Now as a more serious response to you, despite your lack of direction/age/maturity/etc.
If you want to give it a go, you need to find something requiring low capital investment, easy to sell, and with long term to potential to grow exponentially/scalability.
I'd suggest to cut your teeth in business a bit - try prepacking/repacking.
Buy anything in bulk, repack into smaller sizes, add your own label, double/quadruple the markup on product and work on selling the "broken down" product (small packs).
ie: Buy sweets in bulk, pink and white sweets, nuts, mints, etc. Buy premade small clear bags, a scale, and an impulse sealer +/- R500-R1000 spend. Repackage into 30gr or 50gr quantities, create a wire rack display stand (you can buy these ready and add a plastic branded sign to it) and try and market it to local independent retailers for their stores (to be placed near their exits/tillpoints).
Allow them a good markup and yourself a good markup - it is there.
Focus on independent supermarkets and similar stores.
If it works and you're securing a few regular customers, then you're onto something and expand.
If it doesn't, you've learnt a few lessons for less than a grand.
Above assumes you aren't quitting a full time highly paid job for this.
Repacking/prepacking can work on any product - but the sales plan would be different.
Maize, nuts, glycerine, chemicals, cleaning liquids, sweets, rice, biscuits.
It is an easy low cost entry into business.
