How can I improve letting things slide?

Just remember that ignorance is bliss.

I get by life by choosing what to hold on and what to let slide. Unproductive things like grudge need to go, but the responsibility to reach goals must not be forgotten.

I’m not good at it, but I try.

With all due respect, it doesn’t seem as you present yourself here that letting things slide is a major problem.

Listen to this and heed its advice.

Maybe an alternative approach that will work is to not let things slide. Instead, get things done.

Go back to school.
Get a job.
Get outside and walk everyday.

You don’t have a problem with letting things slide, which you do admirably well. What you need is an excuse for letting things slide. Let me see what I can come up with. I’ve got it! See if this works for you. You have an advanced case of arrested development. You are a child trapped in the body of an adult. You have limited impulse control and have extreme difficulty in delaying gratification in order to plan things in advance. Completing your degree or getting a job is simply out of the question. To make matters worse, the Canadian government is aiding and abetting you by making you dependent on them.

I have given up on trying to change you, so I thought the best thing I could do would be to allow you to continue to do what you have been doing (or more accurately, not doing) without any guilt feelings. If this does not work, let me know, so I can try something else.
