As previously said, the time is going to pass anyway, do you want to be getting closer to where you want to be or further from it?
Also don't think of it as a solid goal where you reach it and then that's the end of it.
It's a lifestyle change, it's changing habits for a new healthier way of life.
Change one thing at a time:
Include a daily walk in to your day.
Decide on 3/4 healthy breakfasts and eat these every day, once you've stuck to that move on to lunch ideas.... then dinner.
Whatever your unhealthy indulgence is, reduce it, don't have it every day, have it a few times a week.
This way it becomes part of your life and routine, not a diet or crazy plan you're trying to stick to get results and then reach a finish line.
And start today, not tomorrow, or Monday
