The irony of me posting late on an assignment about time management is not lost on me. With that said, I'll still do my best to be insightful.
Strategies: Don't take on more than you can handle. I would rater produce a one or two high quality products than 5 or 6 that don't fulfill the need. Ask for help if you need it. Sometime we stuck in an area of work and need a hand. Seek out someone who is an expert (or just knows a lot about the matter at hand ) for guidance. Prioritize. The mission comes first. Complete the tasks that will insure the mission we be completed and it will reduce the stress over all
Biggest obstacles: For me it would be spending too much time on the small details. I find myself sometimes fine tuning things that are not essential and add no value to the product.
How I over come the obstacles: Get the project or product completed and make sure it is done right. If you have time, then go back and do the small detail stuff. And, of course, remember your time line so you don't have to rush last minute.
