You are lucky to receive such detailed and accurate advice from the master
@Panther28 !
I can only give you some quick meaningful words... I sense you are very passionate about your work, disciplined, and you think like an engineer in great detail with math.
You need a clearer vision of goals to know when it is on the right track in time more accurately. This will help to know when to complete the current project and move on. Deeper planning/research might be needed prior to launching new projects.
Some projects will need a year or more to show progress, so only then can you start calculating after the initial investment of time. Others you just learned what was needed and it took time.
Everything is going perfectly up until now, good job! Dont stress, learn to enjoy those lessons and years spent becoming wiser.
It was not a waste. You need to slowly replace offline income with online income after squeezing both for awhile longer.
Now utilize ai to boost your productivity to a new high. You can have more thorough approaches now and do it by yourself if needed. You need more creative ideas with more imagination and twists, less logic, math, and competition now.
The LTV/CAC ratio can vary depending on the dollar amounts though, yes it will need to be a key metric in your decision process but 1:1 is different for all projects.
Improving the ratio is another discussion as well. You can feed your stats to ai and have it analyze and recommend adjustments. Good luck!
