+          <p>
+            This marks the (true) beginning of my competitive programming
+            journey. By "true" I mean intentional, focused, daily practice.
+            Driven by my admiration for competitive programmers, love of
+            challenge, and desire for a decent new-grad job, I'm excited to
+            start putting in the work.

+            This webpage will be an archive of everything related to this
+            process, including my practice strategies, setup, shortcomings, logs, and
+            more. For now, I'll be practicing on

+            <a href="https://cses.fi/book/book.pdf" target="_blank">CP Handbook</a> and browsing by related problem tags with
+            ever-increasing difficulty.
