one little thing you can do is every time you are concerned with this, to do so good thing for others, or say a mantra, or create a special present for someone you love 
Who hasn’t? There many ways in which you can clean it up! Shamanic work, Tibetan practices, Reiki, and all previously mentioned.
for me, this a very personal choice and, as you so well mentioned, because this will take some time to happen, it can all change, so doing it in a fun way makes it all worth it! (no waste of time then).It’s a great self-discovery practice, to be answered and unfolded with the magical help of time!
