A few things that work for me...thinking of why I am doing this! I have pictures of loved ones on my desk where I study to keep myself motivated as I know they believe in me. I wear more formal, yet comfortable clothing when studying to feel good and more in confident in myself. I take breaks as I need and step away from my screen when really frustrated at a Q or problem to think and move. you got this! just find what works for you and build on that. I have realized this takes time, and being locked in for the whole time is not reasonable. breathe, you got this.
