Whatever you do, first ask yourself "what are my strengths". Do not just follow some friends which do good money on this or that. Everybody has his / her own strengths and talents.
If it is ok with trade, then you have to do marketing research:
- which product
- target group
- market price
- production cost
Do this for all products you have in mind. It is difficult but worth.
The difference between the market price and production cost will tell you whether to go or shift to another.
all the best
