Starting up is tough, but worthwhile journey. Taking an idea to become reality is a long journey.
Before you think of investors (Angel investors or otherwise), a good starting point would be the following:
- Can you convince your parents (or uncles/aunts) to invest in your idea?
- Can you convince some of your friends to work with you on your idea?
Making the idea work needs money and people. All of this needs convincing - you need to convince a whole lot of people to either give you their hard earned money, or you need to convince people to work on your idea.
I would suggest start on the process of convincing people. Your parents (or uncles/aunts) and friends will ask you enough questions to make you think about other things.
