It's always too early to quit.
Never complain and never explain.
The dog that trots about finds a bone.
Who seeks shall find.
Things do not happen. Things are made to happen.
Go for it now. The future is promised to no one.
Only the educated are free.
Always desire to learn something useful.
If you think you can do it, you can.
By failing to prepare, you are preparing to fail.
I was really into Black Sabbath, but heavy guitars can really be very limiting, it's a great frequency and it's great fun to listen to but on the other hand, musically you can do a lot more without it.
