Sometimes the quickest way to learn is to dive in and make mistakes. Don’t be afraid to make mistakes. Today it’s possible to take 1000’s of photos without the cost of processing film. You can view and delete these photos in moments and continue to shoot.
Go out and take many photos, try different setting as you continue to understand your capabilities and your cameras capabilities. If you make a mistake, learn from it and continue to grow as a photographer. Rinse and repeat this process and you will learn and grow as a photographer faster than… you would if you didn’t (<dah!).
