Those of you who've been following this site for a while will have noticed the new site layout! Hopefully it should be much easier to navigate and faster to load. This is because I haven't just redesigned the layout, but changed the whole way the site is built (switching from Wordpress to Webflow).
This kind of decision is not easy. When you've invested a lot of time, energy and money in a particular way of doing things, it's risky and time consuming to change and rebuild everything from scratch (I used Wordpress for nearly 10 years).
But sometimes it's worth it. If there is a better way, it doesn't make sense to stay on the same path just because of familiarity and sunk costs.
When old decisions start to limit what you can do it's time to investigate other options. The decision to switch should not be taken lightly, but it's worth investing a little bit of time and energy to see if an alternative is viable.
You can apply this to your PhD project, too.
Maybe you made the decision 2 years ago to use a particular technique or software, or maybe you've been struggling for months to make something work and it's just not happening.
Don't change techniques or projects lightly, but also don't let old decisions limit what you can do. Invest a little bit of time and energy to see if an alternative is viable.
