You can be passionate about your PhD and dedicated to your research but still struggle with productivity and struggle to stay motivated.
You’ll have days where you procrastinate or where you question the path you’re on, but that doesn’t mean your passion or dedication has disappeared. It’s just harder to access, that’s all.
Struggle is a part of life, not least during a PhD. It comes and goes like waves on the surface of the sea. But underneath the waves the sea remains more steady.
Your passion and dedication are steady in the same way. Like the waves, your procrastination and struggles will pass in time, creating space for calmer and more focused moments.
Be patient and hold steady.
