Solo-founder here who loves to build and has learnt over a period of time that distribution and understanding the needs is probably 80% of a company. One of the hardest thing for me is not to spend my time just building stuff which are great in my head. Some ground rules I have made are:
" Don’t build until you understand the need", " Be ready to be uncomfortable during times when you are just thinking and chatting with customers", " Have a clear separation in the day when you move from marketing to build mode-helps with context switch". Any other tips, anyone might have?
