Hi @Aerial Smith, in my opinion the @Marshall Vandruff 1994 lectures on fundamentals of perspective are phenomenal, and easier than teaching yourself alone from Technical books. As to fear of mistakes, i admire skateboarders, with that mindset a person just keep trying till land the trick, it doesnt really matter if you land the skateboard trick on first try does it? Hope that helps.

Wonderful question and so universal! Here is what I have to say. Failure in life is inevitable. And bouncing back from failure is the most fundamentally creative thing we can do. By failing, learning and bouncing back from it is how we expand into the best version of ourselves. And the best way to do that is to get comfortable with failure. It's part of the path of success. To help you get moving forward into failure, and cultivate the confidence you need to bounce back from failure, here are some super inspiring quotes about failure. Nicolaides in The Natural Way to Draw says: "The sooner you make you first five thousand mistakes the sooner you will be able to correct them." Seneca says: “It is not because things are difficult that you do not dare. It is because you do not dare that things are difficult.” Tal Ben Shahar says: “We have a haul of fame for achievers but we need a hall of fame for failures.” Thomas Edison: “I have not failed. I’ve just found 10,000 ways that won’t work.” “Many of life’s failures are people who did not realize how close they were to success when they gave up." “We often miss opportunity because it’s dressed in overalls and looks like work.” “Genius is one percent inspiration, ninety-nine percent perspiration.” “When you have exhausted all possibilities, remember this—you haven’t.” “Our greatest weakness lies in giving up. The most certain way to succeed is always to try just one more time.” “If we all did the things we are really capable of doing, we would literally astound ourselves.” John W. Gardner "We pay a heavy price for our fear of failure. It is a powerful obstacle to growth. It assures the progressive narrowing of the personality and prevents exploration and experimentation. There is no learning without some difficulty and fumbling. If you want to keep on learning, you must keep on risking failure - all your life." Teddy Roosevelt "Far better it is to dare mighty things, to win glorious triumphs, even though checkered by failure, than to take rank with those poor spirits who neither enjoy much nor suffer much, because they live in the gray twilight that knows not victory nor defeat." Paulo Coelho "There is only one thing that makes a dream impossible to achieve: the fear of failure." George Bernard Shaw "When I was a young man I observed that nine out of ten things I did were failures. I didn't want to be a failure, so I did ten times more work." Winston Churchhill "Success is going from failure to failure without loss of enthusiasm." Robert F. Kennedy: “Only those who dare to fail greatly can ever achieve greatly.” Thomas Watson, Sr. (founder of IBM): “The fastest way to succeed is to double your rate of failure.” Also I want to share my website with you. It's purpose is to show other artists what it takes to pursue mastery. https://chrisbeaven.com I've been doing art daily for over 3300 days straight and I log EVERYTHING including all my failures. And recently, just like you, I'm going back to the basics because I too have a lot of issues with perspective. Check it out, and if I can help in any way please let me know. chris@unrelentingart.com Thanks for sharing.
