[HardlyCognizant]

Others have have covered most of these, but I'll chime in to agree:

1. Break down required activities into emotionally manageable tasks. (Sometimes this necessitates rendering it down to a level where it seems trivial.)

2. Cut deals with yourself. Permit yourself to procrastinate on one thing, but only if you work on this other priority task. (This works well within a task even, if you have done #1.)

3. Build momentum by completiing easier things first. (This is especially effective if you find satisfaction in checking items off a todo list.)
