James Clear just published a great blog post on Tendai Buddist monks and how this can relate you your own projects. It is well reading the whole article for context but my favourite excerpts are below:
If something is important to you, complete it. If not, kill it.
We all have things that we say are important to us. You might say that you want to lose weight or be a better parent or create work that matters or build a successful business or write a book - but do you make time for these goals above all else? Do your organize your day around accomplishing them?
It doesn't matter how long your goal will take, just get started.
