The most difficult task in my life is saying "no" to someone/something. That just hurt myself and I just asked myself why I can't finish everything with a single "no".
Everytime I remind myself if something is not feasible to me, I should say " no" but I couldn't do it till not. I'm regretted again. I still commit the same mistake.
I'm just confused how should I learn to say "no instead of hurting myself later on.
