Depends on what kind of goal. If I gave a goal of eating 8 hot dogs then a barrier would be a physical will of your body to not eat more. It would be a limit your body can take so it’s different from a mental or other barrier. If you wanted to cross an area of land but there is a fence in the way then that’s another type of barrier. Or there are mental barriers. If you wanted to ask someone out to prom, you may be stopped by a mental barrier of self hatred. Feeling like you’re not good enough.
