It would take some time to change, but the decision to change is instant. If you want to change, change now. Not tomorrow, not next year.
Tomorrow is an excuse, next year is an excuse. Stop making excuses or you’ll never get what you want.
“I’ll exercise more starting tomorrow”
“I’ll go on a diet next year”
“I’ll work harder next month”
Bullshit. Now or never. You do it now, you fail, you learn, you start over. That’s how you change.
Now. Do you want to make excuses, or do you want to make shit happen?
