Project ideas will come to you at some point. Meanwhile, while you're practicing, start making small projects that you know you can finish in a few days, but there's something new to you in it.
I learned by doing games, can't go wrong with that: Minesweeper, Poker/Blackjack (or any card game, implementing the rules of a complex card game is very educational), Tetris, Connect Four, etc. These are not unique projects and won't make you rich but keep on doing them one per week or so until you get a grasp of what you're doing. Just make sure you can and will finish your projects.
Small projects like that are also a very good way to fill your portfolio for your first entry level job. It's no substitute for a good CV but will certainly get the foot between the door compared to someone who doesn't have any work samples to show.
