The Ego Defense Mechanism

I keep rewarding my brain by day dreaming about my end goal without actually working towards it. Fantasies of grandiocity where i'm infinitely better than the person who rejected me, romantically in making them realize what they lost. The general advice is to just focus on self improvement and somehow that's going to meet all my emotional needs. I tried to set dead lines for my goals, but sadly, now i feel only anxious because iam not putting in the work.
