Laziness is just you not wanting something different more than what you have now. That's OK - you won't always be at a place in your life where eating well or exercising is your priority. We all have our own challenges at different times.

When getting in shape is more important than staying the same, then you'll no longer be lazy. It will happen one day. Changing a lot is hard work and needs a lot of motivation - try something smaller like trying to drink more water or get more sleep and you may find that laziness isn't so much of a problem. Good luck @hafiz34
