Where to get money for investment? question to Smart-Lab

Greetings colleagues!
I decided to write on the topic of income and expenses.
I started managing my personal finances in 2017(about). I use a simple program "Journal of Expenses".

It’s simple and I think there’s no point in explaining how to use it, the only thing is that I put CAPITAL in the EXPENSES line, because I pay myself first (my last post).

I also keep a monthly spreadsheet.

I recorded a video on how to use this scheme

I also use the annual scheme (it is shown in the video).
I have a question for Smart-Lab, what schemes do YOU ​​use? and do you use it at all? (I will be very glad to learn something new)
Thanks to all! I'm looking forward to the answers!
