If you have the chance, try and attend a hack weekend like http//:launch48.com . You will meet lots of people who are doing are interested in doing startups. You will get a healthy overview of what it takes in one short weekend. 2. Try and get involved in a startup project even if it is for fun and I promise you that it will jump start something in you.

With your skills (common sense) you could do learn HTML, UX and learn to create mockups e.t.c.

The most important thing you can do now is to take action.

best of luck man
