- Catalogue what you've actually accomplished in terms of stuff created / learned / produced
- Hack it all up into "stuff I will use", "stuff I will reference" and "stuff I will archive"
- Set some hard lines and hard times against deliverables with actual boundaries / units of work - what will you finish, by what date, where does it fit, what's the next stage?
Finally, and the biggest thing for me was: if you can hardline at work, be a professional and produce lots of good stuff on a dealine (assuming you do), you can do that for yourself as well.
Sometimes (as a non-startup type guy) I found it easy to go to work, push past pain barriers, bust serious ass and make some pretty incredible stuff happen, then come home and have a completely different - lazy and shabby - attitude.
As soon as I decided to carry that attitude towards my own goals / projects, it turned a lot of stuff around. I had two or three projects that were half parked for nearly 8 months that I set completion goals for and cleaned up in about 2 months.
Felt great, and made me realise how much you can actually produce when you have a clear idea of what you want to get done.
