I will start with what I think is the most important advice I can give: Apply for A LOT of scholarships. I'm not talking about 10, I'm talking more like 100. I know that sounds crazy, but if you apply for 100 you will end up getting perhaps 2 or 3. Which is probably just what you need.
Some people apply for one or two scholarships and then just give up when they don't get anything. They gave up way too early--you have to be a lot more persistent than that.
And that's another bit of advice. You don't need to be talented or smart to get a scholarship, you just need to be persistent. Money goes unused each year because people don't apply for it, so it might as well go to you.
