Having an environment that's well conducive for learning enables more focus and drains less energy. Whether that may be in the case of time of preferred studying (morning, afternoon, evening?) Or the place where you study (desk? outdoors?)
For me, I prefer to self study in the mornings, but during this summer I got into a late night swing with studying. Having my phone a good distance away is also helpful for me. In the evenings, especially when rain is falling, I love to have tea there. Adapting my study area helps to get me to want to sit there longer to study and overall helps my focus.
What are your guys' ideal study conditions or 'preferred' conditions? (Is chocolate a must have during late night studying, lol)
