Hi, When i started my PhD i was Excited to be doing a PhD but as time has gone by i find it hard to attend university and even harder to focus on my project. I am only 3 months in is this normal or have i made a mistake starting a PhD? Some advice would be nice..

What exactly are you finding hard/demotivating? and yes it's quite normal to experience this when starting something new

I know lots of people who have experienced this. What motivated you to do a PhD? Can you remind yourself of those things, maybe write them down? And maybe as the previous poster has said think about what barriers are causing you to feel demotivated?

Passion for learning new concepts and your subject matter can't be minimized. Perhaps this is not the right time for you to be in school.

Hmm, me again... I have to say that a lot of people experience motivational problems from time to time. It could be a case of just keep pressing on and getting through it. Be careful about making decisions - don't want to make any that you regret. I don't know enough about the situation - but if it is purely motivational (i.e., transient but going on a bit too long and you want to overcome it, you still think you have the same long term goals), then I really encourage you to work through it - keep on going!!!! It often goes in cycles and you will feel motivated again with time :)
I think by way of advice, if I were to put myself in your shoes I would want to do my best to keep going through the motions, see if things improve, and review the situation perhaps after another 3 months or at the end of the year. You may have a different outlook then and not regret not doing anything too hasty! Hope this is helpful.
