1) Job/Tech related: When starting a new project try to think of something new, something you wish to achieve. Like "I'll switch to VIM for this project in stead of TextMate" or "I'll use CoffeeScript here in stead of Javascript". This way you develop yourself further every project and it won't feel as much like you are doing the same thing all over again every time.
2) Start your own company / start as a freelancer. Come on, you can do it ;) It's not for everyone but ever since I've started doing this I haven't had any regret for doing it. You will have lots of extra time and freedom to try new stuff; And once you have the right clients you only need a couple of hours a week to get the same amount of money you now get working your ass off fulltime. Only do this if you know you are good at what you do. Make sure you've worked in the same field before so you know what to expect and be aware of.
3) Not going to work for yourself? Switch jobs once you get bored. I've seen people work at the same job for so long they go into auto pilot and they don't develop any further. In the last 5 years I've had 4 different full-time jobs, at every switch you will learn some new stuff, either tech or business related. No one ever questioned my loyalty and I've had I nice raise every time I started something new.
4) Some big buildings with lots of companies in it have a private parking lot with some guy in a booth checking out if you can park there (most of the time this is for suppliers or people with some kind of access card). Just approach the barrier, smile at the guy in the booth, and raise your hand. Most of the time they will just let you through. If they don't they will ask you why you are there. Just say you are delivering a package for Company X, they will let you through, no further questions asked.
