Reuse, download or create new icon sets for each new project?


I’m a student and don’t know much about working as a UX or UI designer yet.

My question is:
Do designers reuse or download icon sets or do they create own new icons for each project? Is it wrong to reuse or download standard icon sets for a new project?


It depends, if you’re taking about different projects for the same client, then it makes sense to use the same icons for everything.
If you have different clients (projects) and let’s say you are getting paid as a freelancer, it makes sense to only reuse icons when the clients are not from the same industry or they have a competing product. Other than that, it’s always a good idea to either personalize the icons (colour & shape) or use a different set of icons for each project.
