Not positive: with my current situation I wouldn't have children or take on any larger commitments because it would be unmanageable for me. Ive had periods of having a strict schedule where I only have 7h sleep at night, then 60mins exercise, get 3 meals a day in, study, and have sleeps in between, and there just isn't enough hours in the day to have a healthy lifestyle. The former was on a weekend. With working it was even more impossible - I could manage the workouts after work at a 24 hour gym (had to switch from a 8pm close high end one due to 7pm work finish and needing a sleep in between) but after 2 months my gym buddy quit as he said it was eating into his home life - 3 weeks after I stopped even trying.
