Sometimes, you’ve got to let things, relationships and attachments go. If you are focused on achieving a particular goal, you simply cannot chase two things at the same time.
And even when you understand this, you’ve got to know what to prioritize, particularly if prioritizing one thing over the other helps you reach your goal quicker.
The difficulty here, might be choosing what to prioritize from what to cut. However, this is the easy part. An expendable item, relationship or attachment will always give you reasons to cut it, if you look hard enough. And when you find those reasons, let it go.
