Brother.
Try to be more specific. Nobody will advice you couse we don't know where are you? your education level? etc
BTW, if you are somehow out of the town, try kufuga kuku wa mayai mixture na wanyama, within few months you will earn good money.
Also you can start a simple stetionery where you will print, scan, photocopy and sell simple students' materials.
Also remember the kifuku is here, so the rain season soon will start (if not yet where you stay), you can kodi a farm, and try kua mkulima.
What about kununua used bodaboda so it can carry passengers hapo mjini, mama home asikose kodi ya meza?
Have you ever think about being a businessman? Mlanguzi. Taking comodities from town such as vyombo vya jikoni, yeboyebo, etc na kupeleka bush?
Angalizo. During the rain season, kijijini pesa ngumu sana. People direct all their efforts and money to the farming, also remember soon january the school fees will be needed, n sikujuu xmass and new year is here.
Just be care.
Sorry for poor paragraphing.
