How Do You Manage Life with a Full-Time Job and a Side Business?

I’m a full-time office worker in Canada with a medium-low stress job. In addition to this, I also manage a business operating in another country. While I have a part-time clerk overseeing day-to-day operations, I need to be actively involved several times a year, which requires a significant time commitment of about 3-4 hours per day. Outside of work, I’m unmarried with no children but do have some family responsibilities that occasionally cause stress. Lately, I’ve been struggling with task management, leading to a cycle of procrastination, work accumulation, and ultimately, burnout.
