I had a look at your website and it looks amazing. Currently, I am not self-employed but will be next year.
Your question is very interesting and my first thought was: What does it mean to take your company to the next level?
Do you want to employ more people? Do you want to make more money? Do you want to get more customers? Do you want to streamline your processes and be more productive and efficient?
If this is clear, I recommend (because that is my problem) to make less goals than you have planned. We tend to push ourselves massively forward and create preassure which is not helpful.
So, less goals is better.
Then, write down the desired outcome (on a high level).
After that identify criterias that bring you to this desired goal.
You can read about this SMART Goal method in the internet.
At the end write down goals and milestones into a trusted place, i. e. physical notebook, project managment tool, task list manager. It's up to you. But spend some time per week and reflect about the tasks you have completed and which tasks move your project forward. Consistency is the key.
Because it is so easy to start with a project and we are more than happy to finish a project. But the road between start and end is "Consistency".
Does it make any sense to you?
Good luck and best regards.
