The benefits and possibilities that are created by being personally accountable are countless.

This could be a member of your team, a colleague, your boss, a family member or friend.  If you think that you might waiver a bit and need someone to help you stay on track with everything you are committing to doing, then this is a really important step to do.  If you are unsure whether you need someone, think back to previous projects or goals you have committed to and were you successful on your own, or did you give up part way through, or did you have someone nudging you along, reminding you of what you need to do?

This is all about your own determination to succeed.  Again, think back to other projects/goals, what's your staying power, your commitment like?  Do you always complete what you set out to do?  

This could be about setting in regular sessions with your accountability partner to give them updates, progress reports, or perhaps just a regular check in to say you're on track.  And if you are doing this yourself, maybe you will create yourself a timeline, and a 'to do' list and makes sure these are done by certain dates.  Having clarity of what this looks like at this final stage is really important.
