My 2 CENTS... Look around you for clues in needs (may be your own need as an individual), and pass them through the CENTS filter (Control, Entry, Need, Time and Scale). Then Act, Assess, Adjust. If you're not sure, pay a visit to a start-up incubator in Dublin (Accelerators & incubators | Dublin.ie) and chat with people, discuss with incubated start-ups, it may spark ideas. You can then float your ideas on the forum and get feedback from other entrepreneurs/founders.I'm 20 years old and in college in Dublin ,Ireland studying engineering but I'm not sure if I want to give up 5 years of my life just to finally get a job. I would like to become an entrepreneur but I have no ideas as of yet what I would like to do. Any suggestions would be great thanks.
