LOOK FOR THE REASONS WHY YOU NEED TO WORK HARD

You can't force yourself to work hard because you can't see enough reasons to do it, you are ok with your situation, you get satisfied with the mediocre results that you are getting. Look at your money, are you ok with having less? look at your shoes are you ok having a dirty and old shoes? look at your house, are you ok having a noisy environment?

If you want some changes in your life then you need to work hard, the hardest as possible, there is no other way around. If you will not do it then nothing will happen, you will have the same life over and over again which is scary, you know you can do better but you're not doing better because you don't have the habit of working hard.

Work hard now, make it a habit, look for ugly things that you want to change in your life, have as many reasons that you can have to work harder than yesterday.
