I am the same as you Rak. I work 8-4:30 at my regular job and have a hard time having the energy and motivation to put in a solid 4-7 hours at home after work. So on the weekends I find I get up early enough and have the whole day to myself. It kind of sucks being summer and all but it’s a sacrifice for long term gains!
I’m also like rknuppel where I find I do my best work later in the evenings towards midnight.
