Bit by bit (put together) in time will become a mountain

Sometimes you come across something that is just so perfect for what you're going through at the moment, that is what happened when I came across this quote, "Bit by bit (put together) in time will become a mountain." I have had a lot to do lately.  My grandmother recently passed away and as a result of her illness and passing, I've had to put some research related work aside.  On top of that, I've had to add a lot of family related work to my plate, and a very close friend had a milestone birthday in the midst of all this.  I haven't had time to exercise in a week, or relax and decompress.  I've realized again how important my one day a week to have no obligations and just lounge about the house in my pajamas is to me.

Soon I will have more time, once all the memorial arrangements are done and the memorial is over.  Also, I'll have a lot fewer family obligations with my grandmother gone.  Is it selfish to take that time to refocus on myself and my health and wellbeing?  I want to get back to my exercise routine before all this happened, maybe add weekly hikes to the mix.  I want to go back to eating more vegan meals again.  Maybe finish my book and a couple series I've been watching.  I want to do nothing in particular one day a week.  I want work on fixing the broken parts of my car and see movies I've been wanting to see.  I want to look for jobs and have my defense.  I need to be more consistent with myself and make myself more of a priority for these next few months so I can move on with my life.
