to stay motivated for goals

I think I\'m not the type of person who is good at setting goals and trying to stay motivated. When I was a student, I never set goals like what score I got or what rank I would achieve, but I kept studying hard every day because I thought studying was my \"business\" at that time. Another example, if I have a goal of losing weight, I don\'t set specific goal like how many kilos to lose.I just plan such as cutting down a cup of sugar coffee a day, night walking three times a week . Other things are similar to those, not setting goals but doing just things with making plans. I tend to set a main direction, plan activities and then check it out every day. By doing things this way, I can gain good habits, it piles up inside me, whether I reach the goals or not, I can build good habits as my assets for the future. And If I feel I need a very strong motivation for the goal, the goal isn\'t right for me, the goal for me comes to me naturally by my efforts before I feel need to stay motivated.
