Congrats on the first year! Truth is, you've done the hardest part (staying solvent for 12 months) so now you just eed to keep that as a benchmark and it's onwards and upwards!
During those bad times/moments you need to try and remember that you have a commodity that can't easily be measured; time. Time to do what you want, when you want. I, for example, love the cinema. I'll schedule time into my schedule each month to visit the flicks during the day. It can seem odd (and I still struggle after 5 years) with the concept that you don't have to work every hour of the "working day"; that you can pick and choose the times that best suit you.
Finding the work/life balance I think will be my life's challenge. Unless I win the lottery, in which case I'll know what to do ;)
