My advice before switching to something new, is to get first clarity about what is broken with your current system and tool. Decide how things needs to be improved and what a better system would look like for you. Then find a tool that will support your new workflow (instead of the other way around).

This applies to most changes in life and in business.

Incorporating sunk costs into decision-making is a fallacy, but it’s true that switching costs are nonzero, learning curves are real, opportunity cost of time exists.
