Don't let fear of finding funding distract you from pursuing your call. You are NOT alone in this journey and there is help.
For my own quest to raise support, I turned to those who had gone before me, repeatedly. Based on my experience, I recommend the following books. All have the same underlying themes (support-raising is Biblical, get over yourself, and get on with it - only they say it much nicer), but each shares different tidbits and how-to's that you'll find useful.
Even reading just one of these will help you feel more confident and better equipped to raise support and follow your call.
