中文回答：
我决定辞职考博主要是出于对学术研究的浓厚兴趣和职业发展的长远规划。在当前的工作中，我积累了一定的实践经验，但逐渐意识到自己在理论深度和研究能力方面还有很大的提升空间。攻读博士学位不仅能让我系统地学习前沿知识，还能在导师的指导下开展深入研究，进一步提升我的学术水平和创新能力。此外，博士学历也将为我在未来的职业发展中打开更广阔的空间，无论是进入高校、科研机构，还是从事高端技术研发，都能提供更多的机会和可能性。因此，我选择辞职，全身心投入到博士阶段的学习和研究中。
English Answer:
I decided to resign and pursue a PhD primarily due to my strong interest in academic research and my long-term career development goals. In my current job, I have gained valuable practical experience, but I gradually realized that there is still significant room for improvement in terms of theoretical depth and research capabilities. Pursuing a PhD will not only allow me to systematically learn cutting-edge knowledge but also enable me to conduct in-depth research under the guidance of my supervisor, further enhancing my academic and innovative abilities. Additionally, a PhD degree will open up broader opportunities for my future career, whether in academia, research institutions, or high-end technology development. Therefore, I chose to resign and fully dedicate myself to the learning and research involved in the PhD program.
