Is it appropriate to put at the beginning of my PhD thesis a personal quote that very few people would understand ? Could it make my work seem not serious ?
More specifically, it would be lyrics from a song that reflects a personal problem , that my phd helped me to deal with eventually. There is no direct link with the actual content about my research. It just feels right to me to acknowledge what these 4 years of phd brought to my life, beyond pure scientific aspects. 99% of the people reading my thesis would not understand the meaning, and it may even sound quite cryptic for them.
