Just a personal note as long as there is Cenblu, and this is based on observations

Low Effort High Profit
won't be able to be applied in business. investment? yes, if the money is abundant
no matter how the business runs, money keeps circulating, this requires a lot of effort both mentally and in thinking. you have to be smart about how to not reduce quality, not reduce service but still stay profitable in the current conditions
what must be maintained?
1. Equipment
2. Human Resources
If you can't meet one of these? don't expect to be profitable
2 possibilities:
1. Good equipment, no human resources? Break-even point with old equipment, as long as willing to improve, it will actually bring good branding
2. Human resources available but equipment not sufficient? service isn't optimal, quality decreases, worst hit is branding
no matter how the business runs, you have to dare to speculate and be confident. if you're hesitant to upgrade one of these two things, it will slowly kill the business itself.
almost all aspects of life are a form of betting. take it or leave it.
