If you can make one heap of all your winnings
And risk it on one turn of pitch-and-toss,
And lose, and start again at your beginnings.

That was Rudyard Kipling in the poem 'If'. This message is not only to artist but to everyone in life. Sometimes you will know this business, this relationship, this path you are in isn't gonna come out well. But you look at all the energy and time you have put into it and you don't wanna lose that.

Don't hesitate, pick up a brush, brush it off and start again at the beginning. It's not an advice, it's just me thinking aloud.
