      <description>&lt;p&gt;I think I’m gradually getting used to working out now. I don’t feel much soreness after exercising anymore.&lt;/p&gt;
&lt;p&gt;Crazy Thursday again, but I felt much better than before because I slept well last night. I fell asleep easily and didn’t wake up at all until my alarm pulled me out of my dream. The small size #coffee is helpful and no much more effects on sleep.&lt;/p&gt;
&lt;p&gt;So overall, it was a good day.&lt;/p&gt;</description>

<p>Crazy Thursday again, but I felt much better than before because I slept well last night. I fell asleep easily and didn’t wake up at all until my alarm pulled me out of my dream. The small size #coffee is helpful and no much more effects on sleep.</p>
<p>So overall, it was a good day.</p>
<p>I like Apel Derek’s class. He always gives us technical demonstrations or practical examples so we can connect with real-world applications. The class is very engaging. Recently, I’ve also learned a lot from Victor’s class, although I can still feel that he has been quite tired.</p>
<p>Today I attended a Canadian Institute of Mining event that cost 10 dollars. It was really helpful and meaningful. It helped me understand what people in the industry are actually doing. I also felt more confident — I realized that I can do this too, maybe even better.</p>
<p>There was a funny moment. I noticed a guy standing in front of a poster about IoT in mining transportation, so I asked him a few questions. He told me the project was done by his colleague and then he left. Soon after, some other people came over and started asking questions, and somehow I ended up becoming the #presenter.</p>
<p>Chathuranga and Amir found it hilarious. Otherwise, they would probably have been bored at the event.</p>
<p>I also took a box of food to go, and later I gave it to #Zhiqiang when I met him at the university train station.</p>
