@baensaf not the same idea. I always tend to learn from failures so if I failed i need to improve. And thr failure will guide me where the actual problem is in my idea or somewhere else.
My question to you is what is your definition of your idea failing?
Ideas "fail" all the time, but then people re-evaluate, re-assess and re-test or pivot on their idea.
Is it really a failure if you had the courage to bring the idea to life and launch it?
Look for reasons on why it failed -> Learn from it -> See if a Pivot is possible or Build something new.
You never truly fail if you don't give up. It just becomes an experience :)
