G-d began by creating an imperfect world.
It is constantly being improved and becomes more precious to G-d.In each generation, tzaddikim enhance G-d's work.In the end, Mashiach will come and complete everything.Only then will the world be perfect.
Sichot HaRan 239

When you find yourself in the same circumstances,and choose to turn away without repeating your mistake,this alone is called teshuva—true repentance.

"Today I am beginning to attach myself to You."
Start anew each time, because everything goes according to its beginning. If things were already good, they will be even better now. And if they weren't so good before, obviously you should make a new beginning.
Chayah Moharan 437
