Don't try so much to form your character - it's like trying to pull open a tight, tender young rose. Live as you like best and your character will take care of itself.
If I should certainly say to a novice, 'Write from experience and experience only,' I should feel that this was rather a tantalizing monition if I were not careful immediately to add, 'Try to be one of the people on whom nothing is lost.'
Until you try, you don't know what you can't do.
Try to be one of the people on whom nothing is lost!
