Make doing difficult things easy.
- Do the difficult thing early.
- Put on some music while doing what is difficult (if the music doesn't distract).
- Have a short-term reward for doing what is difficult.
- Have the long-term benefit in mind while doing what is difficult.
- Know where the difficult thing falls in the grand scheme of things.
- Use a stopwatch.
- Eliminate distractions before starting. (do not battle distractions while battling what is already difficult).
