The 3 Steps to getting there

1. Separate

Remove everything that does not pertain to the goal at hand from the immediate area.

2. Delegate

Have other people take care of as much as possible-errands, research, call-backs, etc.

If your goal is fundraising or using your medical degree, you need someone to answer the phone besides you.

If you hate cleaning the house, but it's driving you crazy how messy it is, hire someone to clean it. Laundry services will pick up and drop off laundry.

3. Dedicate

Focus on your goal.

Note what and when the distractions arise. Return to steps 1 and 2 until you can follow through with 3 sans interruption.

--
It is not always easy to find the right person/people to help you. In fact, it's usually quite difficult. Start by separating things away that do not pertain to your goal. You may find more things that others (even if they're not the perfect assistants) can help you with than you realised. See how it goes.
