Staying motivated can be hard, especially when you are looking to other people to help. We are all here for our own reasons, and while we all have good intentions to help each other, like somebody else said, we all have things that take us away from this.
Look to yourself for motivation. Set big goals and post them where you can see them everyday multiple times a day, set little goals and track them and then reward yourself in some way every week that you've reached your weekly goals, finally, keep reminding yourself that what you are doing is for yourself and not for other people.
Good luck and stay with it!
