It took me so long to feel okay with using premade stuff. I thought I was cheating or not being a proper "creative" if I wasn't making everything from scratch... but I'm finally figuring out to not worry about that anymore.
Do you use premade stuff in your professional work? I use Canva SO much now, Motion Array, UE5 assets, and so many more things. I only wish I had decided to do this sooner!
