Better time tracking! I had a bit of a wake up call lately where a client was a bit annoyed that I hadn't broken down my hours well enough in an invoice.
I also found that I tended to do more work than I was actually charging for.
So my challenge now is to be more disciplined with time tracking, and to be more transparent with my progress.
For that, I found Harvest to be a pretty good app, which also allows my clients to check in with my daily log, before I actually generate them an invoice, so no nasty cost surprises.
The other good habit I'm working on is having healthy office hours, instead of working from, for example, 3PM to 3AM, which is fun, but not so good when you're getting long in the tooth and have to get up at 6 to get your kid to school, that's pretty rugged TBH ;).
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
