Good for you.
Work hard, don't quit. When it get's to be more than you can handle, work Harder, stay focused.
Imagine the Empire State Building, the Brooklyn Bridge, the Golden Gate Bridge, the Hoover Dam, any and all of the major accomplishments that humanity has brought forward stalling because it was hard.
You could be the architect of the future if you strive to do more than you ever imagined possible and ignoring the nay sayers who say it can't be done. Nothing that has not been done Yet has been or can be done now, so Don't Quit.
There will always be more that demand failure than will ever support you, so focus, and ignore, and study.
Or, just drag and drop something onto a cad program that someone else already did and buy a house, the world needs those guys also.
Chose now, before someone else choses for you.
Good hunting and God Speed to you.
