I have understood one thing.. In ethio, you will find people from every field that complains. You will also find people from every field that I have been satisfied with what they have got. You can really tell which field is profitable in the long run. So I would advise to go for your interest and give it all your energy. Just because someone joined medicine and is now living a stable life, it doesn't mean it will be like this for you. Or just because someone couldn't find a job after 7 years in med school, it doesn't mean it will be like that for you to. The same goes for engineering and other fields. Any field of your interest plus your full energy...that what you should do. Don't listen to what people opinions about each of the fields. Because everyone's path is different
