### input:
i am a 22 year old male. there are many things i am interested in, but never motivated to complete anything. one thing, exercising, at sometime i will be motivated to work out, and have an exercise plan, but after a few months of doing it, i will stop, and not start up again until almost a year or more later. this is one example (out of many things) that i am motivated at one point, then a few weeks or months later i stop doing. i do not feel depressed, i am always smiling/laughing (sometimes for no particular reason), and laid back. i feel like this issue is holding me back from moving on with my life. i have one part time job, want a second job, but not motivated to go out and get one. still live at home, and have no savings. i am not interested in college. the only thing i really want to do as a career (for now) is the military. but i am not ready for that, due to these problems i am having. its been like this for at least 3 years now, and sick of being like this. also i am a quiet person (don t talk much), and try to avoid public places, like going to the store. i usually rather pay for shipping than go to a local store to buy something.
