If you are a solo founder would you share what your week looks like e.g. spend an afternoon on x?
I have productive days and days when I feel like I am scratching around for scraps of leads and SEO. I am currently doing 1k ARR so money is tight and I want to make the best use of my time.
For example, it's good to maintain a few "anchor points" each day to break up your time and help you break out of negative cycles or unproductive moods. Things like going to the gym, maintaining a fixed wake up time or lunch time. This is the discipline side, which helps you to train yourself to stay focused on your goals.
But it's also important to listen to your own body and mind, and do things that make sense to you in the moment. E.g. if you're feeling too tired to work, accept it, go home and try again tomorrow. Avoid burnout. If you scheduled a certain task for 11am but when the time comes you're in the zone on something else, stay in the zone! This is the spontaneity part.
Discipline allows you to be spontaneous without guilt, because you know you'll eventually return to the basic system of moving towards your goal that you've established. Spontaneity allows you to adapt as you go to avoid unforeseen problems or take advantage of unexpected benefits.
That said, on a work day (M-F) my schedule looks roughly like this:
6.30am - wake up 7.30-8.30am - gym 9-9.30am - write down what i did yesterday, what i want to do today 9.30-11.45am - on task 11.45am-12.15pm - lunch 12.15-3pm - on task 3.30-4pm - take a break, make a snack, or go for a walk 4-5.30pm - on task. but if i'm tired go home early. 6-7pm - dinner 7-9pm - relax, read, play music, hang out with my spouse 9pm - wind down, start getting ready for bed
