You are always a valuable, worthwhile human being — not because anybody says so, not because you're successful, not because you make a lot of money — but because you decide to believe it and for no other reason.
The most durable thing in writing is style, and style is the most valuable investment a writer can make with his time.
When making something， always get a few extras — extra material， extra parts， extra space， extra finishes. The extras serve as backups for mistakes， reduce stress， and fill your inventory for the future. They are the cheapest insurance.
