I'd say the biggest things are: consistency of habit, finding something you enjoy, and you can't outrun a bad diet. On habit consistency - start small. People get super depressed because they didn't work out three times that first week. Start with once a week, see how that works for you. Can you build in a second time that week? Do you need to change what time you do the activity, like before work instead of after? Try that and see how it works for you. Make things easy for you by setting your clothes out the night before so there's limited inhibitions on doing the thing you want to do. You'll also need to find something that you enjoy. I'd personally favor a less optimal workout (in terms of working muscle groups, not increased risk of injury) that you enjoy over super-max-get-shredded-tomorrow that's a slog. You'll slowly build into it. For me, my activity was martial arts, I moved away from the dojo and got into weight lifting. I really didn't care for bodyweight fitness, and would find myself looking for excuses to skip or cut the workout short. Be careful when you compare yourselves to others, they could be much further along than you and had different constraints. The third thing is diet. There's tons of articles on proper diet, and for me that's too much stuff to get into at the beginning. What I did was write down and calculate calories for two weeks at the beginning. The first week I ate normally how I felt like. The second I tried to make slight adjustments, still within the realm of things I would eat (basically the "eat this not that"). Those changes were enough for me to get to my desired calorie intake. I don't count macro nutrients, I don't weigh food. It was super intimidating to jump into that, and I didn't want to drag my significant other into my food changes. That being said, maybe entering everything you eat into MyFitnessPal or similar would be helpful for you. Maybe a defined diet regime with preplanned meals is something for you. A friend of mine pays for FancyHands or similar and just sends pictures of what he eats to them and they'll rough out the calorie count into his calorie tracking app. My relative preps everything on Sunday for the week, weighs food, and will not deviate from the diet even for the holidays. It's a bit of an experiment, going back to consistency of habit and something you enjoy. I'd check out /r/fitness, /r/bodyweightfitness, /r/MealPrepSunday/, Strong Lifts, and maybe 4 Hour Body (a friend of mine swore by it, lost 25 pounds) as just different resources you could expose yourself to. You could also decide to do martial arts or basketball or tennis or whatever other sport.
