If something isn’t serving you, let it go. There’s no point sticking with it just because you invested something in the past.
Just because you’ve always kept buying an asset doesn’t mean that you should continue to do so even when you realize it will never be profitable.
Just because you’ve always spent everything you’ve earned doesn’t mean that it’s a good idea to never save anything.
Just because you’ve always smoked doesn’t mean that it’s wise to continue even when you realize that it’s bad for you.
And the same applies to productivity tools, software, projects, roles, companies, beliefs, and dreams.
