Hello, Michael. First, congratulations on that you know your weak points. It is nothing wrong with that. I assume that you have a paper sheet and pen. Write down your goals. Write down time periods. You can not quit smoking without knowing when you will shorten amounts of tobacco.
Think about things and issues which are important to you and how much you are willing to sacrifice to your goals.
It is great to check your motivation. It is personal just for you or do you want to look good in the eyes of your peers? Honesty with yourself always works. You can hate yourself that you lazy, clumsy or boring. Live through moments of it and later on check what inspires you. Ask yourself what do you want to achieve during the day, month or year?
Consistency means that you know where you go. You know your main goals. Ways to achieve them can vary time from time, but your goals will be the same.
When you will accomplish them, be nice to yourself. It does not matter what you did. You did it. After break move on looking for the next destination.
Overall, it is the work with yourself. It is not easy but it pays off.
It is more difficult when you did not see positive role models around. Fortunately, many great books are here. Best minds share their experience and inspiration to look for best qualities in ourselves.
You can find answers in Tim Ferriss book Tools Of Titans. This one book will lift you up and will open new horizons.
