If you do nothing, you earn nothing.
The problem is not time or christification. The problem is in your mind. It does not want to change, therefore it uses negativity to manipulate you.
The antidote is to strengthen the consciousness by studying cause and effect.
Study those negative thoughts and their results. What do they produce in you?
Then, study the teachings and what that study produces in you. Do you become inspired, focused, clear?
Similarly, pick a practice, and do it until you can see the effects, even if they are minor.
You have to experience and confirm the nature of cause and effect. This is the foundation of everything.
