I am interested in implementing data structures in C++ to improve my coding skills. So far, I implemented queue, stack and linked list. I kind of lost my enthusiasm since there is no motivation source other than my self-motivation. Do you have any recommendation to keep yourself motivated when you just code for coding? For instance, I developed a Telegram group bot, that served for a purpose. Informing the group members that I would develop the bot, kept me motivated in the development phase.
