ROUTINE. go at set times on set days, preferably right after work or school so it's tied to something you wouldn't skip. make your program something you like--don't run if you hate it, train low volume if you prefer, use exclusively dumbbells if you want. be realistic with your plan: if you always want to leave after thirty minutes, only plan thirty minute workouts. Consistency brings the benefits. when you start feeling and looking better it'll be easier to keep up the habit.
