Those that NEED encouragement often don't have the inner strength and fortitude to acheive in the arts. To NEED encouragement is to try to fill a void from external sources. That need should be filled from WITHIN.
Those that NEED encouragement often still need a mommy and daddy emotionally. It is a character flaw.
Ansel Adams, Paul Strand, Alfred Steiglitz, Henri Cartier-Bresson, and many other masters had an inner drive, an inner source, a blind ambition. And often their early work was past off as boolsheet. What others thought was of little consequence to them.
Encouragement in and of it's self is not a bad thing. I like encouragement, but the difference is is that I don't NEED it.
It is sad to see adults that need a surragate mommy or daddy to talk them into their photography. They make mistakes and they go off and pout, some even cry, hoping someone will rescue them.
What these weak individuals refuse to understand is that it is actually the burning criticism, the unvarnished truth, that can be the most valuable "encouragement" one can receive. My first few weddings were absolute sheet. The pro I asked to critique my work gave me the raw naked truth about my comps: "these comps are absolute craaap...what were you thinking...".
Now I could've reacted in two different ways: Go away and pout and hope my girlfriend or mommy or daddy would "rescue" me and tell me that that pro dude is an "A-hole" and that my work is "supreme, awesome, and wonderful". Or, I could take trhe pro's words to heart and be objective about it and try to find the truth that may be in his words. I chose the latter and feel better for it.
If you are an adult and reading this, don't be needy ;-) Encourage yourself because it's nobody elses job to do that but yours.
