Growing up scares me
Aspects of it should. But there are other things that make up for it, in true Zen fashion.
Shitty things about being young:
1. Uncertainty.
2. Complete lack of freedom or privacy.
3. Challenged vehicular mobility.
4. Absurd lack of funding.
Shitty things about getting old:
1. All that shit you took for granted when you were young...people expect you to pay for it.
2. Everything hurts...even sleeping. (Your parents are not lying to you about this.)
3. Increasing difficulty in keeping an open mind. It's a daily fight. It's so easy to just close yourself off and become a bitter jaded fuck.
4. Absurd lack of funding. :)
My advice...don't live in fear. If it persists, read H.H. Dalai Lama, and try to get your head where he is at.
