Please what computer package can you suggest for someone like me.

I have decided to use this opportunity to learn something new. Am a student and due to the ongoing ASUU strike I have been at home doing almost nothing. I want to use this opportunity to acquire a new skill in computer.
But I have no Idea what exactly to learn.

I have done my computer appreciation long ago but currently I need to learn something that can fetch me money. (Aside yahoo)

Am currently at MARARABA. I will be thankful for every thoughtful suggestions, ideas and opinions.
