Def.
1 - I know you burned the turkey trying to cook Thanksgiving dinner,
but you can't let that stop you if you really want to become a chef.

Def. 2 - I'd been trying to do 30 minutes of exercise every day, but my work schedule eventually got so busy I could never make it to the gym. Things have calmed down quite a bit recently though and I keep meaning to get back on the horse and go work out again.
