sounds to me like youve got plenty of initiative and get up and go but looking for a better work-life balance.
also sounds like the longer your in that job possibly the more your going to resent it.
but im sure most would agree that any business right now is a consistent grind to keep things moving along and the work coming in. you have multiple jobs as a sole trader and it can get tiring having to keep an eye on all areas of your business.
that said i feel more comfortable in control of future then having it run in the hands of others. and many customers means risk is spread .. and quite easy with some graft to replace customers who have moved away or dies etc.
one things for sure. fortune favors the brave and often when you commit to something ..you find the harder you work the luckier you get.
