Do things now. Don't wish for better times, do it now. Live in the present, do everything you can do now. Make changes in your habits now. Find your road and walk it now. Don't think about the past, you cannot change it. Learn from it and make changes in your life now.
Do the little things, that won't bring results instantly. Do them every day and the result will eventually come to you. Do them even when nobody is watching.
Be patient. Be positive, you can do it. You can achieve your dreams.
Start with theses steps. Don't rush, start with the first step. And then when you are ready to move to the next step. Make little changes every day.
