what's your problem when you undergo a bounty? or can you say what obstacles do you sometimes feel lazy to do or work on a bounty? perhaps all of you have some obstacles which you can share here and might be useful for others. please share your experience 
What a nice question.. The main problem is lack of time - combinig bounties with full-time job is hard you know and sleeping for 5-6 hours a day is definitely not enough.
Another issue is irritation when the bounty admins rapidly change rules or extend the campaign for another 1-1.5 months - I hate this feeling when my plans are being broken.
