If it didn’t work out the first time, the answer isn’t to give up. Success is always built upon lessons and experiences and never are all of them good! Believe me, I've been there!
I hear you when you reach out to me and tell me that it's just too bloody hard, I feel your frustration and you pain that once again it feels like a struggle. Remember not to confuse excitement wth passion, this was a great tip I picked up from The Minimalists (if you haven’t checked them out you should, they’re one of my favourites). Following your passion or mission isn’t always going to be fist pumping, jumping up and down and raving about how AWESOME YOUR LIFE IS. That's excitement, and its short lived. Sometimes you’re gonna have to work through it, when its tough, when you don’t even know if anyone is reading your stuff and you feel thoroughly un-fucking-appreciated.
If you’re passionate it will carry you through those times, if you really love what you do write out your personal why and put it somewhere you can see it because in those times when it feels like you’re dragging yourself through or its not working you’ll have that reminder to hand.
Don’t give up, Try again, and again and again if you have to.
Stop being so hard on yourself, take a break if you need but sooner rather than later, get back to it. Find another way because there always is one.
