Yaa you made a nice decision. Think towards helping your profession with either web development or software. This will make you fall in love with any and inturns make you self employed.

You read Microbiology, a nice course although I don't really know what exactly it entails but every course needs automation to make it better. It is a nice idea.

The software market  is a lucrative field if you are good for what you do.
It's self employing; i mean as a developer, if you advertise your self well ( your work will speak for you), you are bound to always come across one person or the other who wants to upload a website or build one small application or the other.  But you must be good; c#, java,php, mysql etc. 
Also it pays to know hardware too; maintenance & repair, networking etc. All these will take time to acquire but it's worth the effort. Cyber-cafes will always have the need for computer technicians

P.s: you dont have to spend a fortune on i.t centers and the likes. all you need is the right books, committment etc and you'll get there.
