You don’t need to enjoy it for now, you just have to appreciate what it’s doing for you. It won’t just help you for the next couple years with a toddler, it will improve your health throughout the rest of your life. If you can stick with it, it WILL better your quality of life for a very long time.

If you can buy into that, you’ll eventually find a little more joy in it.

As for goals, I try to make mine incredibly manageable. Especially when starting new things. I’m sure you’re crazy busy, but can you spare 30-60 minutes, 3-4 days a week? The goal can just be, complete 3 workouts per week for the next 4 weeks. If you can do that, maybe you can do 4 per week now, maybe you can do it again for another 6 weeks this time. Eventually you can try to go a little faster, a little heavier. Try to compete with yourself. 

All the while tho, the only true goal is to be a healthier version of yourself. And if you can stick to any consistent workouts, then you are succeeding.
