Besides all the good technical advice already mentioned here I'd like to add some things I find very important, as I'm watching over the career progress of 2 junior developers. Take VERY good care of your mental and physical health. Do not overwork yourself. It's a marathon and you will overcome most challenges with time and discipline. You don't have to be a genius/prodigy. Don't put too much pressure on yourself - and it's hard not to due to all the praising of highly successful programmers - but nobody is an overnight success. Enjoy your time off.
