I work on a pet project for one hour per work day. I stop whatever I’m doing at approximately 5 pm and finish when I need to catch the 6:07 pm bus back home.

Contained in this blog post are a few tips for managing your time and staying productive in such a limited time.

State of Play

You may be surprised how much you can actually achieve with just one hour per day. It has certainly surprised me. The work just kind of accumulates gradually over time.

I have now been working on my pet project for two and three quarter years off and on. A total of approximately 520 hours. In standard full time working that is around 13 weeks.

The project is written in C# and currently stands at 6,629 SLOCs including unit tests.

Less Time

If you are prone to perfectionism, you may find that restricting the number hours you have is quite a handy way to circumvent that particular time thief. With just one hour per day, you cannot afford flights of fancy you have to deliver value every time you sit at the keyboard. If you do not, it will become obvious very quickly. Want to port your code over to some fancy new framework, you will lose weeks or months to that. Is the new framework really going to deliver? You’ll probably come to the conclusion that it will not.

Getting Stuck

More precisely, do not get stuck. Getting stuck for one full day on a regular project might lose you one day. On one hour per day, you will lose the best part of two weeks. This will mean that you have to be conservative about the choices that you make. You need good documentation and a means to have problems resolved quickly. Choosing that edgy language / framework nobody knows about is probably not going to work out. Choose mainstream languages and frameworks. You can get help quickly on sites like Stack Overflow. The documentation is likely to exist as well. Anything from a mainstream vendor like Microsoft or Google is also likely to be documented.

Context Switching

The biggest problem with working in very short bursts in something like software development is that in order to be productive you need a lot of context. What am I trying to achieve? What is the design of this part of the software? etc…

There is no easy solution. But, you will get better at context switching by practicing it. Here are some hints that may help you.

The last thing you need to do when you are about to finish for the day is to provide yourself with some nice pointers for the next time you sit down to work. This becomes more important just before a longer break like a weekend or holiday. The hint could be a failing test or a syntax error to remind you what you were working on. The first thing I do everytime I sit down is run the test suite. If the build fails, I fix it. If a test fails, I fix that.

I work on my pet project alone but I still act as if I am working as part of a team. I use the GitHub issue tracker assiduously and track my work in GitHub project. If I don’t know what I’m working on, I just look at the project on GitHub and it will tell me which issue is In Progress. Due to the fact that I work alone and sparingly, I need an external memory of the project to help me speedily get productive each day.

A particularly useful feature of GitHub issues is the Task List. The ability to break down and track the progress of an issue. Task lists give a very fine level of granularity for your project management. Handy for recording where an issue has reached and where it still needs to go.

With just one hour per day, you cannot afford more than a few minutes to understand what you are working on and what you need to do next. If you can optimise your daily start then you will go a long way to making your pet project a pleasurable experience.


Plainly working for just an hour per day does limit the scale of project you can tackle, you may be pleasantly surprised how much you can achieve. If you find yourself prone to perfectionism, you may find restricting your time on a project is a good way to free yourself. You may find that the attitude spills back into your regular work. After all, your regular work is time constrained too.

One of the things you will need to get used to is walking away when you are in the zone. That time when everything feels just right. It is heart breaking sometimes. But you’ve always got tomorrow. Probably.
