When you are really in a moment of self-doubt or lull in creativity… Go to a graveyard and walk through it.
And remember that those are all people who had one life to live. To give their 100%. And now they have passed, all of their mistakes, worries, concerns, fears, judgements, etc. have all been forgotten about.
They are only remembered now by the legacy they created during their one opportunity of life.
Use this to remind yourself how short life can be, and how important it is to use today to its fullest potential, every single day you have the opportunity to.
