What happens when you neglect something you own?
Eventually, that neglected thing falls into disrepair and becomes useless.
Now image that you choose to neglect your fears, your anger, your hate.
Those feelings, like the unused BBQ sitting in your backyard, will become junk. Unusable junk, that just needs to get tossed to the curb.
It will also destroy your hopes and dreams, so keep them maintained, even if you need to put them on the shelf for a while.
