Yes, the worst thing is the huge amount of decision making even over very minor details that has to be done all the time. Coding and maintaining the servers isn't even that difficult. It's all the little stuff like scheduling with clients/vendors suppliers, wondering when is a good time to chase that invoice, which words to change in your proposal for this client, and so all. If you have employees, how to manage them, how to review their work, how to mentor them. It really is death by a thousand paper cuts.
What can help with this is to start building little systems and solve these problems in general.
Dedicate a given day of the month or week for all your meetings so scheduling is simpler.
Chase invoices on the same date every month, chase all invoices that are overdue by some threshold you have set. Just follow the rule, and chase using a template. Perhaps even code the first few chases into an automated system.
Try to avoid customized proposals, use templates for many things. I agree this one is hard.
Managing employees, you have to consider each employee is a force multiplier. The idea here is to invest a day to get a week or similar.
Overall, you need to just invest a limited time into each decision. After that time, go with what feels best even if it isn't perfect and move on. I find the same thing hard myself.
