heh... I work 60 hours 6 days a week and still find time somehow... I just take it out of sleep hours
As for your workout, you're exercising the same muscle groups again way too soon.
You need to leave time to heal in between - you'd be far better off to do each muscle group once a week than doing it 3 times a week.
What will happen is you will be in a permanent plateau, as your muscles will have had no time to heal and grow when you work them again.
split it up differently - maybe chest/triceps on monday, biceps and back on wednesday, and shoulders/legs on friday. You could do abs on monday and friday, but PLEASE do not do abs every day. Work them like every other muscle, preferably with resistance (weighted crunches or leg raises).
Get rid of those high rep sets.
High reps will build endurance, not strength or size. You haven't stated any of your goals, so I don't know if that is what you want or not.
Of course, if you need endurance in your arms for some sport, then by all means keep some high rep sets.
Your goal should be 3 sets of 6-8 reps each, with enough weight that makes the last rep of the last set REALLY hard to finish.
For muscle endurance sets, forget a set number of reps and just do it till exhaustion. Make sure you do that set last though ;
