Don't view getting a job as failing. There's a lot you can learn from the experience. Both in terms of what to do and what not to do.
Don't view it as 'making your parents happy'. It's more about independence and self-sustainability. What would you do tomorrow if your parents decided to cut you off?
If you're working 8 hours a day you'll still have a few hours to work on your own stuff. I work 8 hours a day with a 1 hour commute each way and still manage 1-4 hours a day on personal projects.
My advice? Get out there, get some perspective. You can learn a lot about responsibility and self-discipline from the workplace, maybe that'll help you with your own stuff as well :)
