They're all challenging hacks. I have this quote by Randy Pausch visible all the time on my computer:

"The brick walls are there for a reason. The brick walls are not there to keep us out. The brick walls are there to give us a chance to show how badly we want something. Because the brick walls are there to stop the people who don’t want it badly enough. They’re there to stop the other people."

You have to try, and you have to be persistent
