Planning for the unknown

So I’ve decided my goal this month will be to have 3 paying clients by the end of April.

I love this because all of March I worked on believing that I could actually make money.

Now, I can work on building more trust in myself to do the work.

My question is:

For some of the actions I have “get on sales calls (mini sessions)”

Should I just leave space open for those dates as potential mini session calls?

If I don’t get any sign ups, should I have a secondary thing to do that day?

As a new entrepreneur, planning things that are unknown irritates me because I feel I’m just scheduling things with an unknown outcome for the following week.

How would you advise me to navigate through this?
