One bite at a time."
(Possibly Creighton Adams or Unknown)
That's how I do the jobs I don't want to do. I decide to, at least, just start it and work for a short bit. And, because I'm only committing for that start period, then I'm not overwhelmed about doing the whole job at once. Sometimes, though just getting it started helps me do a bit more than I thought I'd do. Once the job is started then I can come back several times in the day and do short stints at it, taking breaks to do other, more likeable things. :) And by the end of the day, I find I have 'accidentally' gotten a good portion of the overwhelming job done. Basically, I'm tricking myself into getting the job done one bite at a time. That's how I roll. :)
Sneak up on it.
Work on it for 10 minutes, go do something else, swoop back, conquer another 10 minutes. It's only 10 minutes, not the Whole Elephant at once.
And don't beat yourself up about it. If you didn't get to it today! Just simply start the goal again tomorrow. No worries! :)
Be kind to yourself. Encourage yourself like you were talking to your best friend.
Here's a very short youtube illustration.
It helps illustrate accomplishing your "thing".

If you point yourself in the right direction and just get the ball rolling by little nudges and bites then you will be further along in a month or year than you would have been if you waited for that impossible perfect thing before you start "It".
