Going from sharing a one-bedroom place to living in a loft to two people living in a house to me having my own place by myself has kind of mirrored my career... small steps to bigger, to bigger, to now having a steady job.
With every job I've gotten, I've bought myself something. When 'Glee' was picked up, I rented a piano for the year. For smaller victories, I'll go to dinner with a friend, or go for a walk and think about it all. It's important to say to yourself, Today was a good day.
Keep going on hikes, keep having your friends in your life, keep that downtime sacred as well because as hard as you work in any job, it's really nice to have the relaxing de-stressors. Stress is the worst thing. That's the ultimate demise of any good thing.
