Absolutely. I have grown to dislike this often repeated "don't reinvent the wheel" stance. After some thought you realise 100% of mastering any art is based on imitating and rebuilding existing achievements, because that gives us the basis for aiming even higher with our own ideas. When we blindly copy our own "Hello World" program into a text file nobody bats an eye. When a group of musicians play a metal song on classical instruments it's called a cover. But when someone builds their own database to have some fun and get better in-depth understanding of the tech you will always find someone whining about the not-invented-here-syndrome. Effort isn't wasted just because it didn't change the world.
